Effects of earlens lens placement on sound field thresholds, tympanometric measurements and wideband acoustic immittance.

OBJECTIVE: The Earlens is a direct-drive hearing device consisting of a lens which physically displaces the umbo to achieve appropriate gain. The objective is to determine the clinical acceptability of clinical immittance measurements in Earlens wearers. DESIGN: Controlled before-after within-subjects repeated measures study. STUDY SAMPLE: Data is reported for measurements obtained on 15 subjects (average age of 72.2 years) with data from 30 ears. RESULTS: There was a small effect of lens placement on sound field thresholds in most subjects. The largest damping effect of 4 dB was observed at 1000 Hz. An average reduction of 0.17 mL was identified in compliance following lens placement (p < 0.05). An effect of the lens on power absorbance obtained at ambient and peak pressure was found. The lens resulted in an increase in power absorbance at low frequencies (below 500 Hz) and a decrease in the mid to high-frequency range of approximately 500-3500 Hz (p < 0.05). CONCLUSIONS: Lens wear had a small effect on audiometric thresholds and tympanometry for most patients. Clinicians who use compliance and power absorbance should take into consideration lens effects on these measurements. Additional work is required to develop clinical normative ranges of these measures for wearers of the Earlens.

Changes in Orientation Behavior due to Extended High-Frequency (5 to 10 kHz) Spatial Cues.

OBJECTIVES: Current hearing aids have a limited bandwidth, which limits the intelligibility and quality of their output, and inhibits their uptake. Recent advances in signal processing, as well as novel methods of transduction, allow for a greater useable frequency range. Previous studies have shown a benefit for this extended bandwidth in consonant recognition, talker-sex identification, and separating sound sources. To explore whether there would be any direct spatial benefits to extending bandwidth, we used a dynamic localization method in a realistic situation. DESIGN: Twenty-eight adult participants with minimal hearing loss reoriented themselves as quickly and accurately as comfortable to a new, off-axis near-field talker continuing a story in a background of far-field talkers of the same overall level in a simulated large room with common building materials. All stimuli were low-pass filtered at either 5 or 10 kHz on each trial. To further simulate current hearing aids, participants wore microphones above the pinnae and insert earphones adjusted to provide a linear, zero-gain response. RESULTS: Each individual trajectory was recorded with infra-red motion-tracking and analyzed for accuracy, duration, start time, peak velocity, peak velocity time, complexity, reversals, and misorientations. Results across listeners showed a significant increase in peak velocity and significant decrease in start and peak velocity time with greater (10 kHz) bandwidth. CONCLUSIONS: These earlier, swifter orientations demonstrate spatial benefits beyond static localization accuracy in plausible conditions; extended bandwidth without pinna cues provided more salient cues in a realistic mixture of talkers.

Demonstrating Attachment-Based Family Therapy for Transgender and Gender Diverse Youth with Suicidal Thoughts and Behavior: A Case Study.

Suicide is a growing public health issue among adolescents. While the majority of transgender and gender diverse (TGD) youth are healthy, many experience suicidal thoughts and behavior (STB). Due to discrimination and stigma, TGD youth attempt suicide at higher rates then heterosexual, cisgender and even cisgender, LGBQ youth. Despite this vulnerability to suicide, few treatments have been developed and tested for this population. One treatment, attachment-based family therapy (ABFT) has been adapted to work with LGBQ youth and may be promising for TGD adolescents at risk for suicide. This article provides an overview of our ABFT modifications for TGD youth with thoughts of suicide. Specifically, we illustrate how treatment outcomes, in a single case study, relate to processes within clinical treatment tasks. The case study demonstrates the application of these ABFT modifications with a self-identified, gender nonconforming adolescent (who had recently attempted suicide) and his caregivers. Treatment evaluation measures were collected over the course of 24 weeks to illustrate the youth's clinical progress. The youth's suicidal symptoms diminished markedly by the end of treatment. Further, the family reported an increased ability for problem solving and more open communication by treatment conclusion.

El suicidio es un problema de salud pública cada vez mayor entre los adolescentes. Si bien la mayoría de los jóvenes transgénero y de géneros diversos (TGD) son saludables, muchos tienen pensamientos y conductas suicidas. Debido a la discriminación y al estigma, los índices de intento de suicidio en los jóvenes TGD son más altos que en los jóvenes heterosexuales, cisgénero e incluso LGBQ cisgénero. A pesar de esta vulnerabilidad al suicidio, se han desarrollado y se han evaluado pocos tratamientos para esta población. Un tratamiento, la terapia familiar basada en el apego (TFBA), se ha adaptado para trabajar con jóvenes LGBQ y puede ser prometedor para adolescentes TGD en riesgo de suicidio. Este artículo ofrece un resumen de nuestras modificaciones a la TFBA para los jóvenes TGD con pensamientos de suicidio. Específicamente, ilustramos cómo los resultados del tratamiento, en un solo caso práctico, se relacionan con los procesos dentro de las tareas del tratamiento clínico. El caso práctico demuestra la aplicación de estas modificaciones de la TFBA con un adolescente que se identificó como de género no conforme (y que recientemente había intentado suicidarse) y sus cuidadores. Se recopilaron las valoraciones de una evaluación del tratamiento durante el transcurso de 24 semanas para ilustrar el avance clínico del joven. Los síntomas de suicidio del joven disminuyeron notablemente al final del tratamiento. Además, la familia informó una mayor capacidad para resolver problemas y una comunicación más abierta al concluir el tratamiento.

Therapist Adherence to Two Treatments for Adolescent Suicide Risk: Association to Outcomes and Role of Therapeutic Alliance.

In psychotherapy research, adherence refers to the extent to which therapists deliver a treatment as intended. This study examined whether therapist adherence to two different manualized treatments was associated with improved client outcomes and whether the association was moderated by therapeutic alliance. The study sample included 320 video recordings of therapy sessions from 118 cases in a randomized controlled trial (RCT) comparing attachment-based family therapy (ABFT) with family-enhanced nondirective supportive therapy (FE-NST). Recordings were selected from early, middle, and late stages of treatment. The adherence measure consisted of 24 items representing essential therapist interventions from both treatments. Trained raters coded tapes from both therapies. Adolescent self-report of alliance was measured at session 4. Adherence to ABFT was associated with a significant increase in family cohesion at mid-treatment but not at posttreatment. Adherence to FE-NST was significantly associated with an increase in suicide ideation posttreatment. Using therapeutic alliance as a moderator, adherence to ABFT was significantly associated with a reduction in suicide ideation, family conflict, and higher client satisfaction posttreatment. Alliance did not positively affect the association of FE-NST adherence to outcomes. Findings suggest that adherence to ABFT interventions may be better linked to treatment outcomes when adolescents feel a strong alliance with their therapist. Implications for future research and therapist training are explored.

En la investigación sobre psicoterapia, la adhesión se refiere al grado en el cual los terapeutas brindan un tratamiento según lo previsto. Este estudio analizó si la adhesión del terapeuta a dos tratamientos estandarizados diferentes estuvo asociada con mejores resultados en los pacientes y si la asociación estuvo moderada por la alianza terapéutica. La muestra del estudio incluyó 320 videograbaciones de sesiones de terapia de 118 casos en un ensayo aleatorizado controlado donde se comparó la terapia familiar basada en el apego (TFBA) con la terapia de apoyo no directiva optimizada por la familia (TAND-OF). Se eligieron grabaciones de las etapas iniciales, intermedias y finales del tratamiento. El instrumento de medición de la adhesión consistió en 24 ítems que representaban intervenciones esenciales del terapeuta de ambos tratamientos. Un grupo de calificadores capacitados codificaron las grabaciones de ambas terapias. El autoinforme de alianza de los adolescentes se midió en la cuarta sesión. La adhesión a la TFBA estuvo asociada con un aumento considerable de la cohesión familiar en la mitad del tratamiento, pero no después del tratamiento. La adhesión a la TAND-OF estuvo asociada considerablemente con un aumento de la ideación suicida después del tratamiento. Utilizando la alianza terapéutica como moderadora, la adhesión a la TFBA estuvo asociada considerablemente con una reducción de la ideación suicida, el conflicto familiar y una mayor satisfacción del paciente después del tratamiento. La alianza no afectó positivamente la asociación de la adhesión a la TAND-OF con los resultados. Los resultados sugieren que la adhesión a las intervenciones de TFBA puede asociarse mejor con los resultados del tratamiento cuando los adolescentes sienten una alianza fuerte con su terapeuta. Se analizan las implicancias para futuras investigaciones y para la capacitación de los terapeutas.

Barriers and Facilitators to Implementing Attachment-based Family Therapy into a Child Welfare Setting: A Qualitative Process Evaluation.

Child welfare systems (CWSs) worldwide show increased interest in adopting empirically informed clinical strategies to increase treatment effectiveness. Many empirically supported treatments (ESTs) exist, but little is known about EST implementation barriers and facilitators in CWS. This study explored CWS providers' experiences of implementing attachment-based family therapy (ABFT) in home-based services of the Flemish CWS (in Belgium). Sixteen CWS providers (twelve counselors and four supervisors) involved in three home-based services were interviewed. The Consolidated Framework for Implementation Research (CFIR) was used to guide collection, coding, and analysis of interview data. Findings revealed that implementation success was related to ABFT's fit with the CWS's mission, philosophy, and existing practices. CWS providers' belief in the compatibility between ABFT and CWS increased investment in implementation efforts and persistence to overcome challenges and setbacks. Some barriers pertained to the learning of ABFT and some barriers pertained to systems level challenges such as lack of leadership and support, poor coordination with referral sources and other youth care partners, and lack of policy support. For successful expansion of ESTs into CWS settings, various barriers at multiple systemic levels need to be addressed.

Los sistemas de asistencia de menores de todo el mundo demuestran cada vez más interés en adoptar estrategias clínicas empíricamente informadas para aumentar la eficacia de los tratamientos. Existen muchos tratamientos respaldados empíricamente, pero se sabe poco acerca de los elementos obstaculizadores y facilitadores para la implementación de dichos tratamientos en los sistemas de asistencia de menores. Este estudio analizó las experiencias de los prestadores de sistemas de asistencia de menores a la hora de implementar la terapia familiar basada en el apego en los servicios domiciliarios del sistema flamenco de asistencia de menores (en Bélgica). Se entrevistó a dieciséis prestadores de sistemas de asistencia de menores (doce terapeutas y cuatro supervisores) implicados en tres servicios domiciliarios. Se utilizó el "Marco Consolidado para la Investigación de Implementación" (Consolidated Framework for Implementation Research,CFIR) para guiar la recopilación, la codificación y el análisis de los datos de las entrevistas. Los resultados revelaron que el éxito de la implementación estuvo relacionado con la adecuación de la terapia familiar basada en el apego con la misión, la filosofía y las prácticas existentes de los sistemas de asistencia de menores. La confianza de los prestadores de sistemas de asistencia de menores en la compatibilidad entre la terapia familiar basada en el apego y los sistemas de asistencia de menores aumentó la inversión en los esfuerzos de implementación y en la perseverancia para superar dificultades y contratiempos. Algunos obstáculos estuvieron relacionados con el aprendizaje de la terapia familiar basada en el apego y algunos otros con dificultades a nivel de los sistemas, como la falta de liderazgo y apoyo, la mala coordinación con fuentes de derivaciones y con otros acompañantes en el cuidado de los jóvenes, y con la falta de apoyo a las políticas. Para diseminar satisfactoriamente los tratamientos respaldados empíricamente en el marco de los sistemas de asistencia de mejores es necesario abordar diferentes obstáculos en múltiples niveles sistémicos.

Achieved Gain and Subjective Outcomes for a Wide-Bandwidth Contact Hearing Aid Fitted Using CAM2.

OBJECTIVES: The objective of this study was to test the ability to achieve, maintain, and subjectively benefit from extended high-frequency amplification in a real-world use scenario, with a device that restores audibility for frequencies up to 10 kHz. DESIGN: A total of 78 participants (149 ears) with mild to moderately-severe sensorineural hearing loss completed one of two studies conducted across eight clinical sites. Participants were fitted with a light-driven contact hearing aid (the Earlens system) that directly drives the tympanic membrane, allowing extended high-frequency output and amplification with minimal acoustic feedback. Cambridge Method for Loudness Equalization 2 - High Frequency (CAM2)-prescribed gains for experienced users were used for initial fitting, and adjustments were made when required according to participant preferences for loudness and comfort or when measures of functional gain (FG) indicated that more or less gain was needed. Participants wore the devices for an extended period. Prescribed versus adjusted output and gain, frequency-specific FG, and self-perceived benefit assessed with the Abbreviated Profile of Hearing Aid Benefit, and a custom questionnaire were documented. Self-perceived benefit results were compared with those for unaided listening and to ratings with participants' own acoustic hearing aids. RESULTS: The prescribed low-level insertion gain from 6 to 10 kHz averaged 53 dB across all ears, with a range from 26 to 86 dB. After adjustment, the gain from 6 to 10 kHz decreased to an average of 45 dB with a range from 16 to 86 dB. Measured FG averaged 39 dB from 6 to 10 kHz with a range from 11 to 62 dB. Abbreviated Profile of Hearing Aid Benefit results revealed a significant improvement in communication relative to unaided listening, averaging 28 to 32 percentage points for the background noise, reverberation, and ease of communication subscales. Relative to participants' own hearing aids, the subscales ease of communication and aversiveness showed small but significant improvements for Earlens ranging from 6 to 7 percentage points. For the custom satisfaction questionnaire, most participants rated the Earlens system as better than their own hearing aids in most situations. CONCLUSIONS: Participants used and reported subjective benefit from the Earlens system. Most participants preferred slightly less gain at 6 to 10 kHz than prescribed for experienced users by CAM2, preferring similar gains to those prescribed for inexperienced users, but gains over the extended high frequencies were high relative to those that are currently available with acoustic hearing aids.

Exploring Acceptability and Feasibility of Evidence-Based Practice in Child Welfare Settings: A Pilot Study with Attachment-Based Family Therapy.

The Flemish Child Welfare System (CWS) is in great need of a shared empirically informed clinical strategy for working with depressed adolescents and their families. Many evidence-based practices (EBP) exist, but little is known as to whether they can be successfully imported in the CWS. Therefore, the current study explores the implementation of a particular EBP, Attachment-Based Family Therapy (ABFT), in home-based services of the Flemish CWS in Belgium. Specifically, the study focused on (1) the acceptability of ABFT by counselors and whether negative attitudes about EBP can be changed (n = 73 counselors), and (2) the feasibility of implementing ABFT (n = 43 adolescents, 11-17 years old, 72% female) by exploring initial effectiveness. The results suggest that (1) initial negative attitudes of counselors towards ABFT were significantly more positive after attending training and discussions about ABFT, and that (2) ABFT could be used by counselors to successfully reduce adolescent depressive symptoms. Future research should include a control group to draw stronger causal conclusions. Strengths and limitations of the study's design and implications for further dissemination are discussed.

Attachment-Based Family Therapy: A Review of the Empirical Support.

Attachment-based family therapy (ABFT) is an empirically supported treatment designed to capitalize on the innate, biological desire for meaningful and secure relationships. The therapy is grounded in attachment theory and provides an interpersonal, process-oriented, trauma-focused approach to treating adolescent depression, suicidality, and trauma. Although a process-oriented therapy, ABFT offers a clear structure and road map to help therapists quickly address attachment ruptures that lie at the core of family conflict. Several clinical trials and process studies have demonstrated empirical support for the model and its proposed mechanism of change. This article provides an overview of the clinical model and the existing empirical support for ABFT.

Extended High-Frequency Bandwidth Improves Speech Reception in the Presence of Spatially Separated Masking Speech.

OBJECTIVES: The hypothesis that extending the audible frequency bandwidth beyond the range currently implemented in most hearing aids can improve speech understanding was tested for normal-hearing and hearing-impaired participants using target sentences and spatially separated masking speech. DESIGN: The Hearing In Speech Test (HIST) speech corpus was re-recorded, and four masking talkers were recorded at a sample rate of 44.1 kHz. All talkers were male native speakers of American English. For each subject, the reception threshold for sentences (RTS) was measured in two spatial configurations. In the asymmetric configuration, the target was presented from -45° azimuth and two colocated masking talkers were presented from +45° azimuth. In the diffuse configuration, the target was presented from 0° azimuth and four masking talkers were each presented from a different azimuth: +45°, +135°, -135°, and -45°. The new speech sentences, masking materials, and configurations were presented using low-pass filter cutoff frequencies of 4, 6, 8, and 10 kHz. For the normal-hearing participants, stimuli were presented in the sound field using loudspeakers. For the hearing-impaired participants, the spatial configurations were simulated using earphones, and a multiband wide-dynamic-range compressor with a modified CAM2 fitting algorithm was used to compensate for each participant's hearing loss. RESULTS: For the normal-hearing participants (N = 24, mean age 40 years), the RTS improved significantly by 3.0 dB when the bandwidth was increased from 4 to 10 kHz, and a significant improvement of 1.3 dB was obtained from extending the bandwidth from 6 to 10 kHz, in both spatial configurations. Hearing-impaired participants (N = 25, mean age 71 years) also showed a significant improvement in RTS with extended bandwidth, but the effect was smaller than for the normal-hearing participants. The mean decrease in RTS when the bandwidth was increased from 4 to 10 kHz was 1.3 dB for the asymmetric condition and 0.5 dB for the diffuse condition. CONCLUSIONS: Extending bandwidth from 4 to 10 kHz can improve the ability of normal-hearing and hearing-impaired participants to understand target speech in the presence of spatially separated masking speech. Future studies of the benefits of extended high-frequency amplification should investigate other realistic listening situations, masker types, spatial configurations, and room reverberation conditions, to determine added value in overcoming the technical challenges associated with implementing a device capable of providing extended high-frequency amplification.

Attachment-based family therapy for depressed and suicidal adolescents: theory, clinical model and empirical support.

Attachment-Based Family Therapy (ABFT) is a manualized family-based intervention designed for working with depressed adolescents, including those at risk for suicide, and their families. It is an empirically informed and supported treatment. ABFT has its theoretical underpinnings in attachment theory and clinical roots in structural family therapy and emotion focused therapies. ABFT relies on a transactional model that aims to transform the quality of adolescent-parent attachment, as a means of providing the adolescent with a more secure relationship that can support them during challenging times generally, and the crises related to suicidal thinking and behavior, specifically. This article reviews: (1) the theoretical foundations of ABFT (attachment theory, models of emotional development); (2) the ABFT clinical model, including training and supervision factors; and (3) empirical support.

Attachment-Based Family Therapy to Improve Family Functioning in Adolescent Binge-Spectrum Eating Disorders: An Initial Evaluation Via Case Series Design.

Binge-spectrum eating disorders (EDs; bulimia nervosa, binge eating disorder) often develop during adolescence and are associated with serious psychological and physical consequences. Current treatments for adolescents are highly behavioral in nature and while efficacious, many patients do not reach remission indicating that current treatments fail to target a key maintenance factor for EDs. One potential maintenance factor is poor family functioning (FF). In particular, high family conflict (e.g., arguing, critical comments) and low family cohesion (e.g., warmth, support) are known to maintain ED behaviors. Poor FF can (1) cause or exacerbate an adolescent's use of ED behaviors to cope with life stress and/or (2) inhibit parents from being a resource to adolescents during ED treatment. Attachment-Based Family Therapy (ABFT) is specifically designed to improve FF, and thus may be a promising adjunct to behavioral ED intervention strategies. ABFT, however, has not been tested in adolescents with binge-spectrum EDs. Thus, the current study is the first to evaluate a 16-week adapted ABFT treatment for adolescents with EDs (N = 8, Mage = 16.00, 71.43% female, 71.43% White) fusing together behavioral treatment for EDs with ABFT for highest possible impact. Eight families were treated in an open pilot trial to examine treatment feasibility, acceptability, and preliminary efficacy on FF and eating pathology. Overall, findings were promising. ABFT + B treatment was feasible and acceptable and showed preliminary evidence that it could improve FF and ED behaviors. Future research will test this intervention in a larger sample and further examine the role of FF in maintaining ED symptoms.

Maternal psychological stress after prenatal diagnosis of congenital heart disease.

OBJECTIVE: To determine whether prenatal diagnosis of congenital heart disease (CHD) increases maternal stress. STUDY DESIGN: Self-report instruments were administered to mothers carrying a fetus with CHD. Domains included: (1) traumatic stress (Impact of Events Scale-Revised); (2) depression (Beck Depression Index II); and (3) anxiety (State-Trait Anxiety Index). Modifiers included: (1) coping skills (COPE Inventory); (2) partner satisfaction (Dyadic Adjustment Scale); and (3) demographics. Multivariate linear regression models were used to assess relationships between stress measures and modifiers. RESULTS: Fifty-nine mothers (gestational age 27 ± 3 weeks) completed all measures. Clinically important traumatic distress was seen in 39%, depression in 22%, and state anxiety in 31%. Lower partner satisfaction was associated with higher depression (P < .01) and higher anxiety (P < .01). After controlling for partner satisfaction and income, "denial" was most associated with increased traumatic stress, anxiety, and depression (P < .01). CONCLUSIONS: Posttraumatic stress, depression, and anxiety are common after prenatal diagnosis of CHD. Healthy partner relationships and positive coping mechanisms can act as buffers.

Combining attachment-based family therapy and cognitive behavioral therapy to improve outcomes for adolescents with anxiety.

Increases in adolescent anxiety over the past several years suggest a need for trauma-informed, culturally responsive interventions that help teens cope with environmental stressors like those associated with the COVID-19 pandemic. Although abundant evidence supports the efficacy of cognitive behavioral therapy (CBT) in treating adolescent anxiety, not all teens respond positively to CBT. CBT does not typically include strategies that address important family factors that may be impacting the teen's functioning, such as the attachment relationship. Attachment-based family therapy (ABFT) addresses the attachment relationship and other factors that contribute to the adolescent's anxiety and related distress. By enhancing positive parenting behaviors, such as acceptance and validation of the adolescent's distress and promotion of their autonomy, ABFT sessions may repair the attachment relationship and increase the family's ability and willingness to engage in CBT tasks aimed at reducing anxiety. This theoretical paper describes the ABFT model and proposes that implementing ABFT sessions prior to CBT could result in better clinical outcomes for adolescents with anxiety disorders by improving the context within which the anxiety symptoms and treatment are experienced. Given that ABFT is sensitive and responsive to family and other contextual factors, adolescents from marginalized communities and those from less individualistic cultures may find the model to be more acceptable and appropriate for addressing factors related to their anxiety. Thus, a combined ABFT+CBT model might result in better outcomes for adolescents who have not historically responded well to CBT alone.

Attachment-based family therapy in the age of telehealth and COVID-19.

The COVID-19 pandemic has transformed so many aspects of our lives. For psychotherapists, telehealth is likely a permanent part of the future mental health landscape. For family therapists using a manualized treatment, this brings unique challenges and creative opportunities. In this article, we describe the adaptation of attachment-based family therapy (ABFT) in the context of telehealth and COVID-19. ABFT is an empirically supported treatment model designed for adolescents and young adults struggling with depression, anxiety, trauma, and suicide. ABFT is a semi-structured, process-oriented, and trauma-informed family therapy model which presents its own unique challenges and benefits in telehealth environments. We present our adaptations based on years of telehealth clinical experience and address how this model supports the impact of COVID-19 on families.

Attachment-based family therapy: Theory, clinical model, outcomes, and process research.

Attachment-based family therapy (ABFT; Diamond G.S. et al., 2014) is an empirically supported treatment designed to capitalize on the innate, biologically based, caregiving instinct and adolescent need for attachment security. This therapy is grounded in attachment and emotional processing theory and provides an interpersonal, process-oriented, trauma-informed approach to treating adolescents struggling with suicide and associated problems such as depression and trauma. ABFT offers a clear structure and road map to help therapists quickly address the attachment ruptures that lie at the core of family conflict, which can fuel adolescent distress. Several clinical trials and process studies have demonstrated empirical support for the model and its proposed mechanisms of change. In this paper, we provide an overview of the theories underlying the model, the clinical strategies that guide the treatment, the outcome research that demonstrates efficacy, and the process research that explores the proposed mechanisms of change.

Sound Quality Ratings of Amplified Speech and Music Using a Direct Drive Hearing Aid: Effects of Bandwidth.

OBJECTIVE: To determine sound quality for extended bandwidth amplification using a direct drive hearing device. STUDY DESIGN: Prospective double-blind within-subjects repeated measures study. SETTING: University hearing research laboratories. PATIENTS: Fifteen experienced hearing aid users with symmetric mild-sloping-to-severe sensorineural hearing loss. INTERVENTIONS: Sound quality ratings of speech and music passages were obtained using the Multiple Stimulus with Hidden References and Anchors (MUSHRA) protocol after wearing a direct drive hearing aid for at least 4 weeks. Passages were processed to filter out low-frequency (below 123 and 313 Hz) and high-frequency (above 4455, 5583, 6987, and 10,869 Hz) energy. MAIN OUTCOME MEASURES: Comparison of sound quality ratings for speech and music between low and high-pass filter frequencies measured from 0 to 100, where 0 represents "bad" and 100 represents "excellent." RESULTS: Wider bandwidth stimuli received higher sound quality ratings compared with narrower bandwidth stimuli. Conditions with more low-frequency energy (full-band and 123 Hz cut-off) were rated as having higher sound quality. More low-frequency energy in the 123 Hz condition was rated as having higher sound versus the 313 Hz condition (mean difference: 11.2%, p = 0.001). Full-band conditions with more low- and high-frequency energy were higher than the other high-frequency cutoff conditions (mean difference range: 12.9-15%, p < 0.001). CONCLUSIONS: The direct drive system provides higher sound quality of both speech and music compared to narrowband conditions. Sound quality improvements were mainly attributable to low-frequency sound, but stimuli with specific high-frequency content were rated with higher sound quality when additional high-frequency energy was present.

Detection, Speech Recognition, Loudness, and Preference Outcomes With a Direct Drive Hearing Aid: Effects of Bandwidth.

Direct drive hearing devices, which deliver a signal directly to the middle ear by vibrating the tympanic membrane via a lens placed in contact with the umbo, are designed to provide an extension of audible bandwidth, but there are few studies of the effects of these devices on preference, speech intelligibility, and loudness. The current study is the first to compare aided speech understanding between narrow and extended bandwidth conditions for listeners with hearing loss while fitted with a direct drive hearing aid system. The study also explored the effect of bandwidth on loudness perception and investigated subjective preference for bandwidth. Fifteen adult hearing aid users with symmetrical sensorineural hearing loss participated in a prospective, within-subjects, randomized single-blind repeated-measures study. Participants wore the direct drive hearing aids for 4 to 15 weeks (average 6 weeks) prior to outcome measurement. Outcome measures were completed in various bandwidth conditions achieved by reducing the gain of the device above 5000 Hz or by filtering the stimuli. Aided detection thresholds provided evidence of amplification to 10000 Hz. A significant improvement was found in high-frequency consonant detection and recognition, as well as for speech in noise performance in the full versus narrow bandwidth conditions. Subjective loudness ratings increased with provision of the full bandwidth available; however, real-world trials showed most participants were able to wear the full bandwidth hearing aids with only small adjustments to the prescription method. The majority of participants had either no preference or a preference for the full bandwidth setting.

Communication about smoking between depressed adolescents and their parents.

INTRODUCTION: Better understanding of effective parent-adolescent communication regarding tobacco use could inform smoking cessation intervention. METHODS: Semistructured interviews related to communication about smoking were conducted with 15 depressed adolescent smokers and their parents, primarily from urban areas. This study, conducted in 2006-2008, was funded by the Pennsylvania Department of Health. Interview transcripts (N = 30) were coded in QSR N6. RESULTS: Quality of communication, rather than content, seemed to determine whether parental communication was effective. Parents reactivity to, or avoidance of, adolescent smoking presented a barrier to effective communication. In this sample, parents and adolescents were more concerned about problems, such as depression, than smoking. DISCUSSION: Involving parents in adolescent smoking cessation programs may be promising. Parental involvement may include teaching parent-child communication skills, building stronger relational bonds, or helping parents quit simultaneously. Further research is needed to explore whether coupling smoking cessation with depression treatment increases parent and adolescent treatment engagement and effectiveness.

Providers' experiences caring for adolescents who smoke cigarettes.

OBJECTIVE: To describe providers' experiences screening for and counseling adolescent patients who smoke cigarettes. DESIGN: Eight qualitative focus groups were conducted with 51 health care providers in primary care settings. Focus groups were video- and audiotaped; tapes were transcribed for coding by an interdisciplinary team using the constant comparative method. MAIN OUTCOME MEASURES: Providers reported experiences screening for and managing adolescent patients who reported smoking cigarettes. RESULTS: Providers expressed confidence in their ability to screen adolescent patients for tobacco use, particularly as part of regularly scheduled preventive and medical visits. Providers reported difficulty balancing screening for smoking with their concern for maintaining rapport with their adolescent patients. In addition, providers reported that adolescent smoking patterns differed from those of adults, and consequently, providers were not certain at what level of smoking an adolescent required intervention. Furthermore, providers were unclear regarding what interventions were recommended for and effective with adolescents. CONCLUSION: Providers are interested in adolescent evidence-based screening methods and cessation interventions that are supportive of a nonjudgmental and empathic approach to caring for adolescent smokers, particularly those with irregular and situational smoking patterns.

A Randomized Controlled Trial: Attachment-Based Family and Nondirective Supportive Treatments for Youth Who Are Suicidal.

OBJECTIVE: To evaluate the efficacy of attachment-based family therapy (ABFT) compared with a family-enhanced nondirective supportive therapy (FE-NST) for decreasing adolescents' suicide ideation and depressive symptoms. METHOD: A randomized controlled trial of 129 adolescents who are suicidal ages 12- to 18-years-old (49% were African American) were randomized to ABFT (n = 66) or FE-NST (n = 63) for 16 weeks of treatment. Assessments occurred at baseline and 4, 8, 12, and 16 weeks. Trajectory of change and clinical recovery were calculated for suicidal ideation and depressive symptoms. RESULTS: There was no significant between-group difference in the rate of change in self-reported ideation (Suicidal Ideation Questionnaire-Jr; F1,127 = 181, p = .18). Similar results were found for depressive symptoms. However, adolescents receiving ABFT showed a significant decrease in suicide ideation (t127 = 12.61, p < .0001; effect size, d = 2.24). Adolescents receiving FE-NST showed a similar significant decrease (t127 = 10.88, p < .0001; effect size, d = 1.93). Response rates (ie, ≥50% decrease in suicide ideation symptoms from baseline) at post-treatment were 69.1% for ABFT versus 62.3% for FE-NST. CONCLUSION: Contrary to expectations, ABFT did not perform better than FE-NST. The 2 treatments produced substantial decreases in suicidal ideation and depressive symptoms that were comparable to or better than those reported in other more intensive, multicomponent treatments. The equivalent outcomes could be attributed to common treatment elements, different active mechanisms, or regression to the mean. Future studies will explore long-term follow up, secondary outcomes, and potential moderators and mediators.
