RESUMO

Brief exposure to traumatic memories using script-driven imagery (SDI) has been proposed as a promising treatment for posttraumatic stress disorder (PTSD). This study investigated the effect of SDI plus active versus sham deep transcranial magnetic stimulation (TMS) in a secondary analysis of a randomized controlled trial for adults with PTSD (N = 134). Linguistic features of scripts and self-reported distress during a 12-session deep TMS treatment protocol were examined as they related to (a) baseline PTSD symptom severity, (b) trauma characteristics, and (c) treatment outcomes. Linguistic Inquiry and Word Count (LIWC) software was used to analyze the following linguistic features of SDIs: negative emotion, authenticity, and cognitive processing. More use of negative emotion words was associated with less severe self-reported and clinician-rated baseline PTSD symptom severity, r = -.18, p = .038. LIWC features did not differ based on index trauma type, range: F(3, 125) = 0.29-0.49, ps = .688-.831. Between-session reductions in self-reported distress across SDI trials predicted PTSD symptom improvement across both conditions at 5-week, B = -15.68, p = .010, and 9-week endpoints, B = -16.38, p = .011. Initial self-reported distress and linguistic features were not associated with treatment outcomes. The findings suggest that individuals with PTSD who experience between-session habituation to SDI-related distress are likely to experience a corresponding improvement in PTSD symptoms.

RESUMO

OBJECTIVE: Although telehealth psychotherapies have been studied for over 20 years, mental health services remained largely delivered in person until the COVID-19 pandemic forced clinics to reconsider the utility of telehealth psychotherapy. This study aims to compare patient engagement in in-person versus telehealth services in outpatient psychotherapy for mood and anxiety disorders. METHOD: A cohort investigation was conducted, using a propensity score matched sample, extracted from an electronic health record (EHR) to compare engagement in psychotherapy for 762 patients who used in-person services before the pandemic to a cohort of 762 patients who used telehealth psychotherapy after the onset of COVID-19. The authors compared cohorts on initial engagement in psychotherapy services following an initial intake, number of psychotherapy sessions attended, and the rate of missed sessions. RESULTS: There was a 26% increase in the total number of individual psychotherapy sessions attended when the clinics transitioned to telehealth services (p < .001). In addition, patients who received telehealth psychotherapy were five times more likely to not cancel or miss any scheduled sessions (p < .001). CONCLUSION: These results indicate that telehealth services may result in improved treatment engagement for outpatient centers focused on brief evidence-based psychotherapies for mood and anxiety disorders.

RESUMO

OBJECTIVE: To develop a patient-centered text message-based platform that promotes self-management of symptoms of interstitial cystitis/bladder pain syndrome (IC/BPS). METHODS: Adult women with IC/BPS interested in initiating a first- or second-line treatments per American Urological Association guidelines (recategorized as "behavioral/non-pharmacologic treatments" and "oral medicines" in the 2022 version) participated in rapid cycle innovation consisting of iterative cycles of contextual inquiry, prototype design and development. We delivered treatment modules and supportive messages using an algorithm-driven interactive messaging prototype through a HIPAA-compliant texting platform. Patients provided feedback through narrative text messages and an exit interview. Feedback was analyzed qualitatively and used to iteratively revise the platform until engagement ≥ 85% and accuracy ≥ 80% were achieved. The final version consisted of four treatment module categories (patient education and behavioral modification, cognitive behavioral therapy, pelvic floor physical therapy, and guided mindfulness practices) and supportive messages delivered through an automated algorithm over 6 weeks. RESULTS: Thirty IC/BPS patients with moderate symptom bother (median IC Problem Index score 9, range 6-12) participated in five cycles of contextual inquiry. Qualitative analysis identified three overarching concepts that informed the development of the platform: preference for patient centered terms, desire to gain self-efficacy in managing symptoms, and need for provider support. Patients preferred the term "interstitial cystitis" to "bladder pain syndrome" which carried the stigma of chronic pain. Patients reported greater self-efficacy in managing symptoms through improved access to mind-body and behavioral treatment modules that helped them to gain insight into their motivations and behaviors. The concept of provider support was informed by shared decision making (patients could choose preferred treatment modules) and reduced sense of isolation (weekly check in messages to check on symptom bother). CONCLUSION: A patient centered text message-based platform may be clinically useful in the self-management of IC/BPS symptoms.

RESUMO

OBJECTIVES: To describe the characteristics of individuals receiving outpatient rehabilitation for post-acute sequelae of SARS-CoV-2 infection (PASC). Further, to examine factors associated with variation in their psychological and cognitive functioning and health-related quality of life. DESIGN: Observational study. SETTING: Outpatient COVID-19 recovery clinic at a large, tertiary, urban health system in the US. PARTICIPANTS: COVID-19 survivors with persistent sequelae (N=324). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Multivariable logistic and linear regression models were used to examine factors associated with COVID survivors' experience of severe anxiety, severe depression, post-traumatic stress disorder (PTSD), cognitive impairment, and self-reported health-related quality of life. RESULTS: About 38% of survivors seeking care for their persistent COVID symptoms suffered from severe anxiety, 31.8% from severe depression, 43% experiencing moderate to severe PTSD symptomology, and 17.5% had cognitive impairment. Their health-related quality of life was substantially lower than that of the general population (-26%) and of persons with other chronic conditions. Poor and African American/Black individuals experienced worse psychological and cognitive sequelae after COVID19 infection, even after controlling for age, sex, initial severity of the acute infection, and time since diagnosis. CONCLUSIONS: Evidence of consistent disparities in outcomes by the patients' race and socioeconomic status, even among those with access to post-acute COVID rehabilitation care, are concerning and have significant implications for PASC policy and program development.

RESUMO

OBJECTIVES: Age-related variations in emotional, physical, and cognitive health are poorly understood. This multimethod study extends previous work by investigating mechanistic models by which trait mindfulness, perceived stress, and negative affect (NA) influence health outcomes in adults aged 57-87 years old. METHOD: In this cross-sectional study, 119 adults completed clinical interviews, cognitive and gait assessments, the Mindful Attention and Awareness Scale, Positive and Negative Affect Schedule, and Perceived Stress Scale. Gait velocity and executive function (Flanker test of inhibitory control), which are important predictors of global health and functioning in older adults, served as objective health outcome measures. RESULTS: Correlational analyses found that trait mindfulness is positively associated with age, gait velocity, and inhibitory control and negatively associated with NA and perceived stress. NA but not perceived stress was associated with slower gait velocity. PROCESS mediation analyses suggested that those higher in trait mindfulness showed lower NA as a result of less perceived stress, while moderation analyses indicated the relationship between gait velocity and age varied by levels of trait mindfulness. CONCLUSION: Our findings are consistent with a mindfulness stress-buffering model of health. It is plausible that trait mindfulness, which has both mediating and moderating effects on health, might help to promote more successful aging and provide resilience to age-related declines in physical health.

RESUMO

The coronavirus disease 2019 (COVID-19) pandemic resulted in significant increases in insomnia, with up to 60% of people reporting increased insomnia. However, it is unclear whether exposure to risk factors for the virus or worries about COVID-19 are more strongly associated with insomnia. Using a three-part survey over the course of the first 6 months of the pandemic, we evaluated associations between COVID-19 exposures, COVID-19 worries, and insomnia. We hypothesised that COVID-19-related worries and exposure to risk of COVID-19 would predict increases in insomnia. Participants (N = 3,560) completed a survey at three time-points indicating their exposures to COVID-19 risk factors, COVID-19-related worries, and insomnia. COVID-19 worry variables were consistently associated with greater insomnia severity, whereas COVID-19 exposure variables were not. COVID-19 worries decreased significantly over time, and there were significant interactions between change in COVID-19 worries and change in insomnia severity over time. Individuals who experienced increases in COVID-19 worries also experienced increases in insomnia severity. Changes in worry during the COVID-19 pandemic were associated with changes in insomnia; worries about COVID-19 were a more consistent predictor of insomnia than COVID-19 exposures. Evidence-based treatments targeting virus-related worries may improve insomnia during this and future calamities.

RESUMO

INTRODUCTION AND HYPOTHESIS: There is a relative lack of data regarding how patients weigh various factors when choosing a treatment strategy for interstitial cystitis/bladder pain syndrome (IC/BPS). Our aim is to describe patient experience with their current and prior treatments and discuss factors they consider when choosing a treatment. METHODS: Twenty-one women with IC/BPS participated in five focus groups moderated by a psychologist. Focus groups were conducted until thematic saturation was reached. Group discussions were transcribed and independently coded by two reviewers. Emergent themes and concepts were identified using grounded theory methodology. Data on symptoms and beliefs regarding medications were collected using validated questionnaires: Interstitial Cystitis Symptom and Problem Index (ICSI and ICPI) and Beliefs in Medications Questionnaire-Specific (BMQ-S). RESULTS: The median age of participants was 42 years, and all had some college education. Median score (range) for the ICSI was 12 (4, 20) and for the ICPI was 10 (3, 16), indicating moderate symptom burden. Most patients had tried only first- or second-line treatments. The median BMQ-S score was 2, indicating a neutral attitude toward medication. Several themes were identified. Patients expressed interest in self-management of symptoms using a structured care plan that incorporates guided self-care practices and care that can be delivered virtually. Patients desired to minimize treatment side effects by reducing prescription medications and avoiding surgical procedures. Finally, patients had considerable interest in alternative treatments; however, they wanted these treatments to be evidence-based. CONCLUSIONS: Women with IC/BPS have a strong interest in guided programs that teach self-care practices and deliver alternative treatments through remote platforms.

RESUMO

OBJECTIVE: Based on feedback received during post-training consultation within a Prolonged Exposure (PE) implementation initiative, additional assessment training was added to help community providers identify patients who met criteria for posttraumatic stress disorder (PTSD) symptom severity and were considered appropriate for PTSD treatment. The current study investigated the rates of trauma exposure and PTSD in the community sample, as well as the percentage of individuals deemed "appropriate" for PE by community therapists. METHOD: Clinicians involved in the PE Initiative administered the Post-traumatic Diagnostic Scale for DSM-5 (PDS-5) to 10,260 individuals across 13 community agencies. Clinicians were also asked to report whether patients were perceived as appropriate for PE. RESULTS: Consistent with our hypothesis, the rates of potential PTSD in Philadelphia community mental health (58.2% of our total sample) far exceeded national averages (8.3%). Contrary to our hypothesis, 100% of patients who scored above the clinical cutoff for PTSD were considered appropriate for PE by their community clinician. CONCLUSIONS: The results of this study emphasize the high prevalence of PTSD among individuals presenting for treatment to community mental health centers. Despite common misconceptions that patients are often perceived as ineligible or not appropriate for PE, 100% of patients in the PE Initiative who scored above the clinical cutoff for PTSD were considered good candidates for treatment according to their clinicians. This suggests that with sufficient training and post-training consultation, as provided in this community initiative, community clinicians may be more likely to perceive PE as an appropriate treatment option.

RESUMO

Previous studies have identified that ongoing consultation and organizational support are key factors in sustaining evidence-based implementation initiatives in community mental health. Clinician-level factors likely influence implementation but are not well delineated. This study assessed clinician-reported professional development incentives for participating in consultation in prolonged exposure (PE) therapy to guide future evidence-based practice (EBP) initiatives. Providers in the PE initiative (N = 22) completed a survey asking about their motivations to participate, the impact of consultation on the implementation of PE and their professional development goals, and the impact of organizational-level support on their goals and on organizational-level clinician turnover. Of the respondents, 10 had decided to pursue additional training to become PE consultants at their agencies. Providers (response rate = 22/35) reported joining the PE Initiative to learn an evidence-based practice in general (not PE specifically) and increase their skill in treating posttraumatic stress disorder. Providers largely found ongoing consultation helpful and reported that consultation provided the feedback and support necessary to achieve their professional goals. Providers who decided to pursue PE consultant training reported that expanding upon supervision and clinical skills were strong motivators. Providers largely attributed clinician turnover within the PE Initiative to organizational-level factors. Ongoing consultation facilitated providers' professional development goals. The survey identified several areas for further exploration, including how consultation can reduce clinician turnover, and how taking on additional responsibility within implementation initiatives can facilitate provider engagement in the EBP.

RESUMO

Persons living with HIV (PLWH) are significantly more likely to meet criteria for a psychiatric disorder compared to the general population. To our knowledge there are no prior studies that report rates of psychiatric diagnosis documentation in electronic medical records (EMRs) of PLWH. The goal for this study was to report the rates of a variety of psychiatric diagnoses among PLWH in electronic medical records. Participants (n = 2,336) were enrolled in the Center for AIDS Research (CFAR) Longitudinal Database study at the University of Pennsylvania, Philadelphia, PA. Diagnostic codes were extracted from the EMR for depressive disorders, alcohol and substance use disorders, PTSD, sleep disorders, and adjustment disorders and were compared to rates from national epidemiological studies. Rates of Major Depressive Disorder in the EMR were comparable to prior reports on HIV-infected samples. In contrast, rates of PTSD, substance use disorders, alcohol use disorders, adjustment disorders and insomnia from the EMR were all markedly lower compared to national estimates for HIV-infected samples. While clinicians appropriately documented evidence of Major Depressive Disorder, other psychiatric comorbidities were largely overlooked. These findings suggest a potential bias in how clinicians either detect or document psychiatric disorders in PLWH.

RESUMO

Persons living with HIV (PLWH) are significantly more likely to die by suicide compared to the general population. This is the first study to examine the impact of posttraumatic stress disorder (PTSD), major depressive disorder (MDD), insomnia, and substance use disorders on suicidal ideation/behavior among PLWH using electronic medical record (EMR) data. We also evaluated the mutual influence of interactions between PTSD and substance use disorders on suicide risk, consistent with the substance abuse, violence exposure, and HIV/AIDS "SAVA" syndemic model. Participants (n = 2336) were HIV+ individuals recruited through the Center for AIDS Research (CFAR). Participants provided informed consent for extraction of their EMR. As hypothesized, univariate analyses revealed that PTSD, MDD, insomnia, alcohol and other substance use disorders (cocaine abuse and cocaine dependence, opioid abuse and dependence, cannabis abuse, other psychoactive substance abuse and dependence, and polysubstance use disorder) were each positively associated with suicidal ideation/behavior. Also as hypothesized, a multivariable analysis found that alcohol and cocaine dependence, MDD, and PTSD were significant predictors of suicidal ideation/behavior. Contrary to hypotheses, none of the interactions between PTSD and substance use disorders were significantly associated with suicidal ideation/behavior.

RESUMO

The unprecedented effects and duration of the COVID-19 crisis are likely to elevate the population's level of anxiety due to psychological stress, economic hardship, and social isolation. This effect may be especially potent for individuals with preexisting mental health conditions, such as posttraumatic stress disorder (PTSD). Prolonged Exposure (PE) therapy is a highly effective treatment for PTSD across trauma-exposed populations, and has been implemented effectively via telehealth. Nevertheless, PE implementation via telehealth may require specific adaptations during the COVID-19 crisis due to public health mandates calling for sheltering in place and physical distancing. This paper discusses strategies for implementing PE for PTSD during the COVID-19 pandemic, which may also be applied to other situations in which physical distancing must be considered.

RESUMO

OBJECTIVE: Adolescents with posttraumatic stress disorder (PTSD) are at higher risk for suicide compared to adolescents without PTSD. This study aimed to explore whether PTSD treatment reduces suicidal ideation in adolescents and whether the degree of reduction in PTSD was associated with reduction in suicidal ideation. METHODS: Adolescent females with PTSD from a sexual assault (55% Black, 15.3 years, SD = 1.5) were randomized to either prolonged exposure therapy for adolescents (PE-A, n= 31) or client-centered therapy (CCT, n = 30). They reported on suicidal ideation, depression and PTSD at pre- and post-treatment, every therapy session, and follow-up, and about 40% endorsed suicidal ideation at baseline. RESULTS: There was a significant reduction in a single-item measure of suicidal ideation during treatment across all participants. The Time in Treatment × Condition interaction was significant (p < .05, d = 0.52), indicating a significantly steeper reduction in suicidal ideation in PE-A compared to in CCT. The degree of reduction in PTSD (ps < .05, d = 0.26-0.54) and depression symptoms (ps < .05, d= 0.54-0.81) in treatment and follow-up was associated with the speed of suicidal ideation reduction in treatment and follow-up. CONCLUSIONS: Adolescents randomized to PE-A had significantly faster reductions in suicidal ideation compared to those randomized to CCT. Greater reduction in PTSD and depression symptoms were associated with faster reduction in suicidal ideation. Clinically, this study demonstrates that adolescents who have suicidal ideation without current intent may benefit from PE-A.

RESUMO

BACKGROUND: Few studies have investigated the patterns of posttraumatic stress disorder (PTSD) symptom change in prolonged exposure (PE) therapy. In this study, we aimed to understand the patterns of PTSD symptom change in both PE and present-centered therapy (PCT). METHODS: Participants were active duty military personnel (N = 326, 89.3% male, 61.2% white, 32.5 years old) randomized to spaced-PE (S-PE; 10 sessions over 8 weeks), PCT (10 sessions over 8 weeks), or massed-PE (M-PE; 10 sessions over 2 weeks). Using latent profile analysis, we determined the optimal number of PTSD symptom change classes over time and analyzed whether baseline and follow-up variables were associated with class membership. RESULTS: Five classes, namely rapid responder (7-17%), steep linear responder (14-22%), gradual responder (30-34%), non-responder (27-33%), and symptom exacerbation (7-13%) classes, characterized each treatment. No baseline clinical characteristics predicted class membership for S-PE and M-PE; in PCT, more negative baseline trauma cognitions predicted membership in the non-responder v. gradual responder class. Class membership was robustly associated with PTSD, trauma cognitions, and depression up to 6 months after treatment for both S-PE and M-PE but not for PCT. CONCLUSIONS: Distinct profiles of treatment response emerged that were similar across interventions. By and large, no baseline variables predicted responder class. Responder status was a strong predictor of future symptom severity for PE, whereas response to PCT was not as strongly associated with future symptoms.

RESUMO

INTRODUCTION: Distress intolerance (DI), one's perceived or behavioral incapacity to withstand distress, is implicated in psychopathology and smoking. This study evaluated the effect of DI on smoking reinforcement in the context of a carbon dioxide (CO2) biological challenge. METHODS: Adult daily smokers (n = 90; 48.9% female) were randomized to receive a single inhalation/breath of 35% CO2-enriched air (n = 45) or compressed room air (n = 45). Perceived DI was assessed before the challenge. Smoking reinforcement was examined via average post-challenge puff volume across puffs and at the puff-to-puff level. RESULTS: Higher DI was associated with an increased average puff volume (b = -4.7, p = .031). CO2 produced decreased average puff volume compared with room air (b = -7.7, p = .018). There was a DI* condition interaction (ƒ2 = 0.02), such that CO2 decreased average puff volume compared with room air in smokers with higher DI (b = -13.9, t = -3.06, p = .003), but not lower DI. At the puff-to-puff level, there was a significant interaction between DI, condition, and cubic time (b = 0.0003, p =. 037). Specifically, room air produced large initial puff volumes that decreased from puff to puff over the cigarette for high- and low-DI smokers. CO2 produced persistent flat volumes from puff to puff over the cigarette for higher DI smokers, whereas CO2 produced puff volumes like that of room air in lower DI smokers. DISCUSSION: Findings suggest DI heightens smoking reinforcement generally, and in the context of intense cardiorespiratory distress, is associated with stable and persistent smoking. DI is a promising therapeutic target that, if addressed through psychological intervention, may improve cessation outcomes by decreasing smoking reinforcement. IMPLICATIONS: This study contributes to our understanding of the relationship between DI and smoking reinforcement, via examining these processes in response to acute cardiorespiratory distress. Specifically, we found that smokers who are less tolerant of distress, as opposed to those who are more tolerant, evince a decrease in average puff volume, and consistently low puff-to-puff volume, in response to a biological stressor. These findings suggest that smokers high in DI alter smoking behavior following acute cardiorespiratory distress, perhaps to reduce overstimulation, yet also persist in smoking in a manner that suggests an inability to achieve satiation.

RESUMO

The current study examined the role of trauma-related guilt on posttraumatic stress disorder (PTSD) symptom change during prolonged exposure therapy (PE) as well as the efficacy of PE in reducing three dimensions of guilt (responsibility, wrongdoing, and lack of justification) during treatment. Participants were 331 active duty U.S. military personnel seeking treatment for PTSD who were randomized to one of four groups: massed PE (10 sessions delivered over 2 weeks), spaced PE (10 sessions delivered over 8 weeks), present-centered therapy (PCT; 10 sessions delivered over 8 weeks), or minimal contact control (MCC; weekly therapist phone check-in for 4 weeks). The results showed that baseline guilt did not predict reductions in PTSD symptoms for spaced PE or for PCT, ps = .178-.387, ds = -0.02-0.07. Treatment condition (massed PE vs. MCC; spaced PE vs. PCT) did not moderate reductions in guilt for spaced PE versus PCT. Guilt decreased significantly over treatment in all groups, p < .001 to p = .038, ds = -0.19 to -0.42, except concerning justification in the spaced PE and PCT groups, p = .140, d = -0.10. The findings suggest that guilt may be reduced significantly following active PTSD treatment and attention control and that PTSD recovery is not impacted by baseline levels of trauma-related guilt in military personnel with PTSD, although reported levels of guilt were low to moderate in this sample.

RESUMO

BACKGROUND: Most individuals experience more than one trauma. Hence, it is important to consider the count and types of traumas (polytraumatization) in relation to post-trauma mental health. METHOD: The current study examined the relation of polytraumatization patterns to PTSD clusters (intrusions, avoidance, negative alterations in cognitions and mood [NACM], and alterations in arousal and reactivity [AAR]), depression, and impulsivity facets (lack of perseverance, lack of premeditation, negative urgency, sensation seeking) using a web-based sample of 346 participants. Age, gender, race, and ethnicity were covariates. RESULTS: Results of latent class analyses indicated a three-class solution: Low Experience, Moderate Experience - Predominent Threat/Indirect PTEs (Moderate Experience), and High Experience - Predominant Interpersonal PTEs (High/Interpersonal). Multinomial logistic regression results indicated that ethnicity and gender were significant covariates in predicting Low versus High/Interpersonal Class, and Moderate Experience versus High/Interpersonal Class membership, respectively. The High/Interpersonal Class had higher scores on most PTSD clusters, depression, and the impulsivity facets of lack of perseverance and negative urgency compared to the other classes. The Low and Moderate Experience Classes differed on PTSD's avoidance and AAR clusters (lower in the former). CONCLUSIONS: Individuals exposed to multiple PTE types, particularly interpersonal traumas, may be at risk for more severe post-trauma symptoms.

RESUMO

Violation of unconditioned stimulus (US) expectancy during extinction training may enhance associative learning and result in improved long-term extinction retention compared to within-session habituation. This experiment examines variation in US expectancy (i.e., expectancy violation) as a predictor of long-term extinction retention. It also examines within-session habituation of fear-potentiated startle (electromyography, EMG) and fear of conditioned stimuli (CS) throughout extinction training as predictors of extinction retention. Participants (n = 63) underwent fear conditioning, extinction and retention and provided continuous ratings of US expectancy and EMG, as well as CS fear ratings before and after each phase. Variation in US expectancy throughout extinction and habituation of EMG and fear was entered into a regression as predictors of retention and reinstatement of levels of expectancy and fear. Greater variation in US expectancy throughout extinction training was significantly predictive of enhanced extinction performance measured at retention test, although not after reinstatement test. Slope of EMG and CS fear during extinction did not predict retention of extinction. Within-session habituation of EMG and self-reported fear is not sufficient for long-term retention of extinction learning, and models emphasizing expectation violation may result in enhanced outcomes.

RESUMO

BACKGROUND: Although self-efficacy (SE) and outcome expectancy (OE) have been well researched as predictors of outcome, few studies have investigated changes in these variables across treatments. We evaluated changes in OE and SE throughout treatment as predictors of outcomes in a large sample with panic disorder, generalized anxiety disorder, social anxiety disorder, or posttraumatic stress disorder. We hypothesized that increases in SE and OE would predict reductions in anxiety and depression as well as improvement in functioning. METHODS: Participants (mean age = 43.3 years, SD = 13.2, 71.1% female, 55.5% white) were recruited from primary care centers throughout the United States and were randomized to receive either Coordinated Anxiety Learning and Management (CALM) treatment - composed of cognitive behavioral therapy, psychotropic medication, or both - or usual care. SE and OE ratings were collected at each session for participants in the CALM treatment (n = 482) and were entered into a structural equation model as predictors of changes in Brief Symptom Inventory, Anxiety Sensitivity Index, Patient Health Questionnaire (PHQ), and Sheehan Disability Scale outcomes at 6, 12, and 18 months after baseline. RESULTS: The best-fitting models predict symptom levels from OE and SE and not vice versa. The slopes and intercept of OE significantly predicted change in each outcome variable except PHQ-8. The slope and intercept of SE significantly predicted change in each outcome variable. CONCLUSION: Over and above absolute level, increases in SE and OE were significant predictors of decreases in symptoms and increases in functioning. Implications for treatment are discussed, as well as future directions of research.
