Psychometric properties of the Ryerson Social Anxiety Scales in individuals with social anxiety disorder.

BACKGROUND: Although numerous self-report measures of social anxiety exist, most instruments assess symptom severity by examining the range of social situations that provoke anxiety, rather than the distress and impairment associated with social anxiety. The Ryerson Social Anxiety Scales (RSAS; Lenton-Brym, A. P., Rogojanski, J., Hood, H. K., Vorstenbosch, V., McCabe, R. E., & Antony, M. M. (2020). Development and validation of the Ryerson Social Anxiety Scales (RSAS). Anxiety, Stress, & Coping, 33(6), 642-660), a measure assessing breadth of social anxiety inducing situations and severity of associated distress and impairment, was recently developed to fill this gap. The present study is the first to investigate the psychometric properties of the RSAS in a clinical sample. METHOD/DESIGN: Participants included 110 individuals with a principal diagnosis of social anxiety disorder (SAD). A subsample of participants (n = 23) completed cognitive-behavioural group treatment (CBGT) for SAD. RESULTS: The RSAS demonstrated excellent internal consistency. Examination of the correlations between the RSAS and other conceptually related and distinct measures supported the convergent and discriminant validity of the RSAS. The RSAS was also sensitive to changes in severity of social anxiety following CBGT. CONCLUSION: The RSAS is a reliable and valid instrument for assessing the severity of SAD.

Development and validation of the Ryerson Social Anxiety Scales (RSAS).

Background: Extant self-report measures of social anxiety primarily assess the breadth of social situations in which respondents feel anxious, rather than assessing severity in terms of the distress and impairment that individuals experience due to their social anxiety symptoms. This paper describes the development and validation of the Ryerson Social Anxiety Scales (RSAS; Rogojanski et al., 2019; see Appendix), a new measure for assessing both the breadth of situations that trigger social anxiety and the severity (i.e., distress and impairment) associated with social anxiety, across two studies. Method/Design: Two samples of university students (N = 501 total) completed demographic and self-report symptom measures. In Study 1, participants completed the RSAS and several other measures of psychological symptoms. In Study 2, participants completed the same measures and were also assessed for the presence of Social Anxiety Disorder (SAD) using a semistructured clinical interview. Results: Across both samples, the RSAS demonstrated excellent internal consistency and incremental validity. It consistently emerged as a unique predictor of psychosocial impairment. In Study 2, increases in RSAS scores were associated with increased odds of having SAD. Conclusions: The RSAS has robust psychometric properties and fills an important gap among available measures for assessing SAD severity.

The relation between adverse childhood experiences and moral injury in the Canadian Armed Forces.

Background: There is increasing evidence that moral injuries (MIs) may affect the mental health of Canadian Armed Forces (CAF) members and veterans. Despite knowledge suggesting that MIs are related to multiple negative mental health outcomes, including the onset of post-traumatic stress disorder (PTSD), it is unknown whether pre-traumatic variables, including the presence of childhood abuse, are related to MIs. Objective: This study seeks to investigate the potential relationship between adverse childhood experiences and later onset MI in military members. Methods: Thirty-three patients newly admitted to an inpatient unit for treatment of trauma-related disorders received a standardized self-assessment package, including the PTSD Checklist for DSM-5 (PCL-5), the Moral Injury Events Scale (MIES; adapted for the Canadian context), and the Adverse Childhood Experiences Questionnaire (ACE-Q), which is a retrospective measure of childhood abuse. Results: Analyses revealed a significant relation between childhood emotional abuse and the presence of MI in adulthood. Specifically, emotional abuse during childhood was correlated with total score on the MIES (p = 0.006) and with its two subscales, perceived betrayals (p = 0.022) and perceived transgressions (p = 0.016). These correlations remained significant when controlling for age and gender. Conclusions: Among CAF members and veterans, childhood events are related to the presence of MI during adulthood. These preliminary data are provocative in suggesting that emotional abuse during childhood may increase the likelihood of endorsing MI during adult military service. Further work is needed to identify pre-traumatic variables that may serve to increase risk or enhance resilience to the development of MI in military members.

Antecedentes: Existe un aumento de la evidencia que los daños morales (MIs, por sus siglas en inglés) pueden afectar la salud mental de los miembros de las Fuerzas Armadas Canadienses (FAC) y veteranos. A pesar que el conocimiento sugiere que las MIs están relacionadas con múltiples consecuencias negativas en la salud mental, incluyendo el inicio del trastorno de estrés postraumático (TEPT), se desconoce si variables pre-traumáticas, incluyendo la presencia de abuso en la infancia, están relacionadas con MIs. Objetivo: Este estudio busca investigar la relación potencial entre experiencias infantiles adversas y el posterior inicio de MIs entre los miembros militares. Método: Treinta y tres pacientes nuevos admitidos a una unidad hospitalaria para tratamiento de los trastornos relacionados con trauma, recibieron un paquete estandarizado de auto-evaluación, incluyendo la lista de chequeo para TEPT del DSM-5 (PCL-5), la Escala de Eventos de Daño Moral (MIES por sus siglas en inglés, adaptada para el contexto canadiense) y el Cuestionario de Experiencias Adversas Condiciones Infantiles (ACE-Q por sus siglas en inglés). Resultados: Los análisis revelaron una relación significativa entre abuso emocional en la infancia y la presencia de MI en la adultez. Específicamente, el abuso emocional durante la infancia estuvo correlacionado con el puntaje total del MIES (p= 0.006) y con sus dos sub-escalas, percepción de traición (p=0.022) y percepción de transgresiones (p= 0.016). Estas correlaciones permanecen significativas cuando se controlan por edad y sexo. Conclusiones: Entre los miembros y veteranos FAC, los eventos en la infancia están relacionados con la presencia de MI durante la adultez. Estos datos preliminares son provocativos en sugerir que el abuso emocional durante la infancia puede incrementar la posibilidad de refrendar MI durante el servicio militar en la adultez. Es necesaria más investigación para identificar las variables pre-traumáticas que pueden servir para incrementar el riesgo o aumentar la resiliencia a desarrollar MI entre los miembros militares.

Dissociative symptoms mediate the relation between PTSD symptoms and functional impairment in a sample of military members, veterans, and first responders with PTSD.

Background: Posttraumatic Stress Disorder (PTSD) is associated with significant functional impairment in important areas, including interpersonal relationships and occupational or educational roles. Preliminary evidence suggests that the dissociative subtype of PTSD (PTSD+DS), characterized by marked symptoms of depersonalization and derealization, is associated with increased functional impairment and disease severity, including among military members and veterans diagnosed with PTSD. Similarly, first responders (e.g. police, fire, paramedics) have also been found to experience dissociative symptoms. Despite these findings, little work has investigated whether dissociative symptoms are related to heightened functional impairment among these populations. Objective: We examined the relation between functional impairment and symptom level variables, including dissociative symptoms of depersonalization and derealization among military members, veterans, and first responders with probable PTSD. We further investigated the hypothesis that dissociative symptoms mediate the relation between PTSD symptomatology and functional impairment. Method: Eighty-one medical charts of inpatients at a residential PTSD treatment programme were accessed via retrospective review. Sixty-two were included in the present analyses. Comparison of means on symptom measures between first responders and military members/veterans were conducted, followed by correlational and mediation analyses. Results: Compared with first responders, military members and veterans showed higher levels of derealization, functional impairment, alexithymia, anxiety, and depression. Within the total sample, dissociative symptoms emerged as the strongest correlate of functional impairment and, among the dissociative symptom clusters, derealization symptoms demonstrated the strongest relation with impairment. Mediation analyses revealed that total dissociative symptoms and derealization symptoms significantly mediated the relation between PTSD symptoms and functional impairment. Conclusions: These findings highlight the importance of assessing and treating dissociative symptoms, consistent with the dissociative subtype of PTSD, among military members, veterans, and first responders with PTSD. Successful recovery on a functional and symptomatic level may necessitate treatment of dissociative symptoms, particularly derealization.

Planteamiento: El trastorno por estrés postraumático (TEPT) se asocia con un deterioro funcional significativo en áreas importantes, incluidas las relaciones interpersonales y los roles ocupacionales o educativos. La evidencia preliminar sugiere que el subtipo disociativo de TEPT (TEPT + SD), caracterizado por síntomas marcados de despersonalización y desrealización, se asocia con mayor deterioro funcional y gravedad de la enfermedad, incluso entre miembros militares y veteranos diagnosticados con TEPT. Del mismo modo, también se ha encontrado que los profesionales en intervención inmediata (por ejemplo, policías, bomberos, paramédicos) también experimentan síntomas disociativos. A pesar de estos hallazgos, pocos han investigado si los síntomas disociativos están relacionados con una mayor deficiencia funcional entre estas poblaciones.Objetivo: Examinamos la relación entre el deterioro funcional y las variables de nivel de síntomas, incluyendo síntomas disociativos de despersonalización, desrealización entre miembros militares, veteranos y profesionales en intervención inmediata con un probable TEPT. Además investigamos la hipótesis de que los síntomas disociativos median la relación entre la sintomatología del TEPT y el deterioro funcional.Método: Se accedió a ochenta y un historiales clínicos de pacientes hospitalizados en un programa residencial de tratamiento de TEPT mediante un análisis retrospectivo. Sesenta y dos fueron incluidos en el presente análisis. Se realizó una comparación de los medios de medición de síntomas entre los profesionales en intervención inmediata y los militares y veteranos, seguida de análisis de correlación y mediación.Resultados: En comparación con los profesionales en intervención inmediata los miembros del ejército y los veteranos mostraron niveles más altos de desrealización, deterioro funcional, alexitimia, ansiedad y depresión.Dentro de la muestra total, los síntomas disociativos surgieron como el correlato más fuerte del deterioro funcional y, entre los grupos de síntomas disociativos, los síntomas de desrealización mostraron la relación más fuerte con el deterioro. Los análisis de mediación revelaron que los síntomas disociativos totales y los síntomas de desrealización mediaban significativamente en la relación entre los síntomas de TEPT y el deterioro funcional.Conclusiones: Estos hallazgos resaltan la importancia de evaluar y tratar los síntomas disociativos, coincidentes con el subtipo disociativo del TEPT, entre los militares, los veteranos y los profesionales en intervención inmediata con TEPT. El éxito de su recuperación a nivel funcional y sintomático puede requerir el tratamiento de los síntomas disociativos, en particular, la desrealización.

Cognitive-behavioral therapy for chronic insomnia.

OPINION STATEMENT: Psychological and behavioral therapies should be considered the first line treatment for chronic insomnia. Although cognitive behavioral therapy for insomnia (CBT-I) is considered the standard of care [1], several monotherapies, including sleep restriction therapy, stimulus control therapy, and relaxation training are also recommended in the treatment of chronic insomnia [2]. CBT-I is a multimodal intervention comprised of a combination of behavioral (eg, sleep restriction, stimulus control) and cognitive therapy strategies, and psychoeducation delivered in 4 to 10 weekly or biweekly sessions [3]. Given that insomnia is thought to be maintained by an interaction between unhelpful sleep-related beliefs and behaviors, the goal of CBT-I is to modify the maladaptive cognitions (eg, worry about the consequences of poor sleep), behaviors (eg, extended time in bed), and arousal (ie, physiological and mental hyperarousal) perpetuating the insomnia. CBT-I is efficacious when implemented alone or in combination with a pharmacologic agent. However, because of the potential for relapse upon discontinuation, CBT-I should be extended throughout drug tapering [4]. Although the treatment options should be guided by the available evidence supporting both psychological therapies and short-term hypnotic treatment, as well as treatment feasibility and availability, treatment selection should ultimately be guided by patient preference [5]. Despite its widespread use among treatment providers [6], the use of sleep hygiene education as a primary intervention for insomnia should be avoided. Sleep hygiene may be a necessary, but insufficient condition for promoting good sleep and should be considered an adjunct to another empirically supported treatment.

Rethinking safety behaviors in insomnia: examining the perceived utility of sleep-related safety behaviors.

Harvey's cognitive model of insomnia (2002a) proposes that sleep-related safety behaviors play a central role in the maintenance of insomnia because such maladaptive coping strategies are thought to reinforce threat-based appraisals of the likelihood and consequences of poor sleep. Research to date has assessed the frequency of safety behavior use in those with insomnia only; however, in addition to the frequency of occurrence, the function of safety behaviors (i.e., a belief that they will prevent a feared outcome from occurring), may be an important consideration. The purpose of this study was to examine sleep-related safety behaviors based on an expanded theoretical understanding of such behaviors across psychological disorders; that is, by examining both their frequency and perceived utility. Undergraduate students (N=376) completed an online survey about their sleep, mood, and use of sleep-related safety behaviors. Insomnia severity was associated with a greater perceived need to use safety behaviors (i.e., utility) but not with frequency of safety behavior use. Higher perceived utility of safety behaviors was also associated with unhelpful beliefs about sleep, fear and avoidance of fatigue, and both general and sleep-specific helplessness. These results suggest that these behaviors and the associated underlying maladaptive beliefs may be important targets in cognitive behavioral therapy for insomnia. The current study extends the existing literature and refines the concept of safety behaviors in insomnia to include both the function and frequency of these behaviors.

Effects of safety behaviors on fear reduction during exposure.

The use of safety behaviors has been considered one of the primary maintaining mechanisms of anxiety disorders; however, evidence suggests that they are not always detrimental to treatment success (Milosevic & Radomsky, 2008). This study examined the effects of safety behaviors on behavioral, cognitive, and subjective indicators of fear during exposure for fear of spiders. A two-stage design was used to examine fear reduction and approach distance during an in vivo exposure task for participants (N=43) assigned to either a safety behavior use (SBU) or no safety behavior use (NSB) condition. Overall, both groups reported significant and comparable reductions in self-reported anxiety and negative beliefs about spiders at posttest and 1-week follow-up. Participants in the SBU group approached the spider more quickly than did participants in the NSB condition; however, participants in the SBU condition showed a small but significant decrease in approach distance at follow-up. These results call for a reconceptualization of the impact of safety behaviors on in vivo exposure.
