Does mental contamination mediate the association between childhood trauma and obsessive-compulsive symptoms in adults?

BACKGROUND: Previous research has shown that individuals with obsessive-compulsive disorder (OCD) and OCD symptoms have higher rates of childhood trauma. Although it has been suggested that this relationship is due to mental contamination that developed in response to trauma, no studies have investigated the associations between childhood trauma, mental contamination, and OCD, and none have examined whether the relationship between childhood trauma and OCD is mediated by mental contamination. OBJECTIVE: We hypothesized that OCD, childhood trauma, and mental contamination are positively correlated, and that mental contamination would mediate the association between childhood trauma and OCD symptoms PARTICIPANTS AND SETTING: We tested these hypotheses in a sample of 245 individuals, which comprised 158 MTurk workers recruited via CloudResearch.com and 87 individuals recruited through social media with OCD diagnoses or OCD symptoms above the clinical cutoff on the Obsessive-Compulsive Inventory-Revised. METHODS: Participants completed online self-report questionnaires on childhood trauma, mental contamination, and OCD symptoms. RESULTS: The results revealed statistically significant positive correlations between childhood trauma, mental contamination, and OCD, and statistically significant total and indirect effects for the simple mediational model. Exploratory re-analyses with participants who had high OCD symptoms (n = 87) showed similar results. CONCLUSIONS: Our research shows that the association between childhood trauma and OCD may be explained by mental contamination. We recommend that mental contamination should be assessed and addressed in OCD patients with a history of childhood trauma.

Reducing seclusion and restraint in an acute adolescent psychiatric ward: A feasibility study.

WHAT IS KNOWN ON THE SUBJECT: Restraining and secluding health consumers for safety reasons continue to be used in psychiatric inpatient facilities even though they have no therapeutic value and have negative effects on consumers, families and staff. Six Core Strategies (6CS) for reducing seclusion and restraint have been developed to address this problem but there are very few effectiveness studies in inpatient adolescent psychiatric facilities. WHAT THE PAPER ADDS TO EXISTING KNOWLEDGE: We used a mixed methods approach to evaluate the implementation of 6CS in an adolescent psychiatric facility. The implementation was successful. It eliminated the use of seclusion, substantially reduced the use of restraints and significantly reduced staff absenteeism. Using thematic analysis on feedback surveys, we identified five dominant themes that described consumers' and carers' experiences during their stay at the facility: communication, service delivery, flexibility, consistency and internal feeling states. WHAT ARE THE IMPLICATIONS FOR PRACTICE: This study provides support for the feasibility of a comprehensive and broad-based intervention program such as 6CS to reduce seclusion and restraint practices in inpatient mental health facilities. This study also demonstrates the value of using surveys to gather consumer and carer feedback and improve outcomes for service users. ABSTRACT: Introduction Seclusion and restraint practices are routinely used in psychiatric facilities but are controversial for ethical, legal and safety reasons, and can cause significant harm to consumers, staff and organisations. Six Core Strategies (6CS) for reducing seclusion and restraint were developed to address this problem but very few studies have examined their effectiveness in adolescent settings. Aim/Question To evaluate the implementation of 6CS in an adolescent inpatient psychiatric facility. Method We retrieved archival data from an acute adolescent psychiatric ward that implemented the 6CS. Using a mixed methods approach, we evaluated outcomes on the use of seclusion and restraint, nursing staff sick leave and feedback surveys. Results Findings showed an elimination of seclusion, and a significant reduction in restraint use and staff absenteeism in the 12 months after project implementation. Thematic analysis of feedback survey responses identified communication, service delivery, flexibility, consistency and internal feeling states as dominant themes in consumers' and carers' experience on the unit. Discussion The 6CS is feasible and may be effective in reducing seclusion and restraint, which in turn may have a positive impact on staff wellbeing. Implications for Practice Implementation of the 6CS with executive support, combined with staff and programmatic changes at a local level is recommended.

The role of insight, social rank, mindfulness and self-compassion in depression following first episode psychosis.

Gaining awareness of psychosis (i.e., insight) is linked to depression, particularly in the post-acute phase of psychosis. Informed by social rank theory, we examined whether the insight-depression relationship is explained by reduced social rank related to psychosis and whether self-compassion (including uncompassionate self-responding [UCS] and compassionate self-responding [CSR]) and mindfulness buffered the relationship between social rank and depression in individuals with first episode psychosis during the post-acute phase. Participants were 145 young people (Mage  = 20.81; female = 66) with first episode psychosis approaching discharge from an early psychosis intervention centre. Questionnaires and interviews assessed insight, depressive symptoms, perceived social rank, self-compassion, mindfulness and illness severity. Results showed that insight was not significantly associated to depression and thus no mediation analysis was conducted. However, lower perceived social rank was related to higher depression, and this relationship was moderated by self-compassion and, more specifically, UCS. Mindfulness was related to depression but had no moderating effect on social rank and depression. Results supported previous findings that depressive symptoms are common during the post-acute phase. The role of insight in depression for this sample is unclear and may be less important during the post-acute phase than previously considered. Supporting social rank theory, the results suggest that low perceived social rank contributes to depression, and reducing UCS may ameliorate this effect. UCS, social rank and possibly mindfulness may be valuable intervention targets for depression intervention and prevention efforts in the recovery of psychosis.

The association between OCD and Shame: A systematic review and meta-analysis.

BACKGROUND: Due to rumination and self-criticism over unwanted obsessions and repetitive rituals, shame is a common emotion experienced by individuals with obsessive-compulsive disorder (OCD). Shame is also theorized to have relevance to unacceptable thoughts in OCD. However, empirical research looking at the relationship between OCD and shame is still emerging and findings have been mixed. OBJECTIVES: Our review systematically examines the association of shame with OCD and unacceptable thoughts. METHODS: The last updated search was conducted across five databases between 27 and 29 February 2022. The final selection included 20 papers, 18 of which were used in the primary meta-analysis to calculate pooled effect sizes between OCD and shame measures using a random effects model. In a separate analysis, three papers were used to calculate pooled effect sizes between shame and OCD symptom dimensions also using a random effects model. RESULTS: The meta-analyses identified a significant, moderate and positive correlation between total OCD and shame scores r = .352, 95% CI [0.260, 0.438]. In addition, significant, weak and positive relationships were found between shame and three OCD symptom dimensions: unacceptable thoughts r = .252, 95% CI [-0.467, 0.9708], harm obsessions r = .224, CI [-0.190, 0.638] and symmetry concerns r = .200, CI [-0.108, 0.509]. LIMITATIONS: Shame measures in the reviewed studies were not specific to OCD, and between-study variance in the analyses examining unacceptable thoughts was significant. CONCLUSIONS: Our findings support a medium positive relationship between shame and OCD. As shame in OCD can be a barrier to seeking treatment and impair quality of life, it is imperative to address this emotion through psychoeducation, assessment and treatment.

Paternal pregnancy-related anxiety: Systematic review of men's concerns and experiences during their partners' pregnancies.

BACKGROUND: Up to 25 % of expectant parents experience anxiety symptoms. Pregnancy-related anxiety is characterised by concerns and worries specific to pregnancy, childbirth, and the transition to parenthood. While pregnancy-related anxiety is well-researched in women, the exact nature of this construct in men is unclear. The purpose of the current review was to examine men's concerns, worries, and fears during pregnancy and gain an understanding of their experiences during pregnancy. METHODS: An integrative review design was adopted, using thematic content analysis to synthesise findings from quantitative and qualitative studies. Quality appraisal of the quantitative studies used the AXIS appraisal tool. The Critical Appraisal Skills Program (CASP) checklist was used for the qualitative studies. RESULTS: A comprehensive search of nine databases led to inclusion of 14 quantitative and 41 qualitative studies. Ten dimensions of paternal pregnancy-related anxiety were identified: childbirth concerns, attitudes towards childbirth, baby concerns, acceptance of pregnancy, partner concerns, relationship concerns, worry about self, transition to parenthood, attitudes towards health care professionals, and practical and financial concerns. The pregnancy transition was characterised by mixed emotions and conflicted experiences for fathers. LIMITATIONS: Generalizability of review findings was limited by poor reporting of demographic information by many included studies, exclusion of studies not published in English, and focus on heterosexual relationships. CONCLUSIONS: Expectant fathers may experience anxiety symptoms characterised by excessive worry across multiple domains of pregnancy-related concerns. Clinicians play an important role in identifying and supporting fathers with pregnancy-related anxiety and addressing the sense of exclusion often experienced by them.

Is it as good as being in person? The effectiveness of a modified clinician facilitated buried in treasures group for hoarding disorder using video teleconferencing.

The COVID-19 pandemic has necessitated the use of video-teleconferencing (VTC) for psychological treatments but VTC effectiveness studies are sparse. We examined treatment outcomes for a modified Buried in Treasures (BIT) group program for hoarding disorder (HD) delivered via VTC. Participants were 10 individuals with HD. Hoarding severity was evaluated at pre, mid, post, and six-month follow-up. Results showed significant decrease in hoarding symptoms over time (with an average decrease of 32%). The dropout rate was low (9%) and 30% of participants were fully recovered at follow-up. These results support the adaptation of in-person BIT for HD into a VTC format.

Should personal practice be part of cognitive behaviour therapy training? Results from two self-practice/self-reflection cohort control pilot studies.

There are good theoretical and empirical grounds to suggest that personal practices (PPs; e.g., self-practice/self-reflection [SP/SR] programmes, meditation programmes and personal therapy) can have a positive impact on therapist skills and client outcomes. However, to date, a weakness in many PP studies is the lack of cohort control groups. The two pilot studies reported in this paper examined SP/SR programmes integrated into postgraduate psychology training and are the first to include cohort control groups. Study 1 compared outcomes of students assigned to either SP/SR (n = 17) or a cognitive behaviour therapy (CBT) book study group (n = 13) during their first clinical placement. Study 2 compared outcomes of students who completed the SP/SR programme as part of CBT training (n = 12) with participants who completed the same CBT training in the previous year without an SP/SR programme (n = 17). Significant improvements in therapist confidence for the SP/SR groups were found in both studies. Study 2 also showed significantly higher therapist self-awareness and lower burnout scores in the SP/SR group. These studies are limited by their small sample size and the lack of random allocation. Nevertheless, they provide preliminary empirical evidence demonstrating large effects of PP on trainees' personal and therapist selves and offer a basis for further research using randomized controlled designs with larger sample sizes.

Emotion-Oriented Coping Style Predicts Self-Harm in Response to Acute Psychiatric Hospitalization.

Psychiatric hospitalization can cause significant distress for patients. Research has shown that to cope with the stress, patients sometimes resort to self-harm. Given the paucity of research on self-harm among psychiatric inpatients, a better understanding of transdiagnostic processes as predictors of self-harm during psychiatric hospitalization is needed. The current study examined whether coping styles predicted self-harm after controlling for commonly associated factors, such as age, gender, and borderline personality disorder. Participants were 72 patients (mean age = 39.32 years, SD = 12.29, 64% male) admitted for inpatient treatment at a public psychiatric hospital in Sydney, Australia. Participants completed self-report measures of coping styles and ward-specific coping behaviors, including self-harm, in relation to coping with the stress of acute hospitalization. Results showed that younger age, diagnosis of borderline personality disorder, and higher emotion-oriented coping were associated with self-harm. After controlling for age and borderline personality disorder, higher levels of emotion-oriented coping were found to be a significant predictor of self-harm. Findings were partially consistent with hypotheses; emotion-oriented but not avoidance-oriented coping significantly predicted self-harm. This finding may help to identify and provide psychiatric inpatients who are at risk of self-harm with appropriate therapeutic interventions.

Object attachment in hoarding disorder and its role in a compensatory process.

Hoarding disorder (HD) is characterised by compulsive acquisition and extreme difficulty discarding possessions, resulting in clutter that substantially impacts upon functioning. Heightened object attachment is a central feature of HD according to prominent theoretical models. We review current research on the nature and function of object attachment in HD. In particular, we describe growing evidence that object attachment in HD is a compensatory response to unmet relatedness needs, and recent research underscoring the insecure nature of object attachment in hoarding. Critical gaps include the lack of longitudinal studies and research examining the effects of interpersonal interventions on object attachment in HD. Further elucidation of the compensatory process in HD will have important implications for the treatment of this disabling disorder.

Object attachment and emotions in hoarding disorder.

BACKGROUND AND AIMS: Object attachment is a core feature of hoarding disorder (HD), but it also occurs in people without HD. It is therefore critical to clarify differences between normal and abnormal object attachment. Although previous studies show that HD is associated with high emotional reactivity, no study to date has examined the nature and intensity of discrete emotions in people with and without HD in relation to object attachment. METHOD: Individuals with HD (n = 93) and matched controls (n = 93) were recruited via MTurk. They identified and described a possession of low monetary value that they were emotionally attached to and found difficult to discard. Participants rated their object attachment and the intensity of emotions when imagining being with the object (Scenario A) and irretrievably losing the same object (Scenario B). RESULTS: Unexpectedly, there were no significant between-group differences on object attachment; however, the HD group experienced more incongruent emotions about their possessions; they reported significantly higher disgust, anxiety and anger than controls when they imagined being with their chosen object (Scenario A) and were more relaxed compared to controls when the object was lost (Scenario B). There were no significant differences between groups on congruent emotions (i.e., positive emotions in Scenario A or negative emotions in Scenario B). CONCLUSION: People with and without HD experience similar emotional attachment for sentimental items but people with HD experience more mixed emotions, consistent with an insecure object attachment.

Unpacking the construct of emotional attachment to objects and its association with hoarding symptoms.

BACKGROUND AND AIMS: The appetitive aspects of hoarding disorder, such as the compulsive acquisition and saving of objects, are akin to other behavioral addictions. Underpinning these appetitive features is the strong emotional and sentimental attachments that hoarding sufferers have for their possessions. Different facets of object attachment have been identified including anthropomorphism, insecure object attachment, possessions as an extension of identity, possessions as a repository of autobiographical memories, and possessions as a source of comfort and safety. The aim of this study was to examine the association between each of these facets and hoarding symptoms independent of non-sentimental hoarding beliefs, depression, and anxiety. METHODS: Participants were 532 individuals recruited via Turkprime who completed online self-report questionnaires on hoarding symptoms, hoarding beliefs, depression, anxiety, and the facets of object attachment. Pearson's correlations and hierarchical multiple regression analyses were conducted. RESULTS: The results showed that all facets of object attachment were positively correlated with hoarding symptoms. After accounting for other non-sentimental hoarding beliefs, depression, and anxiety, three facets made significant unique contributions to hoarding symptoms: insecure object attachment, anthropomorphism, and possessions as a repository of autobiographical memories. DISCUSSION AND CONCLUSIONS: Based on these findings, we propose a compensatory model to explain how the different facets of object attachment may be implicated in hoarding. Further research into ways of reducing anthropomorphism, insecure object attachment, and possessions as memories are warranted.

Meta-analysis of the effects of third-wave behavioural interventions on disordered eating and body image concerns: implications for eating disorder prevention.

Third-wave behavioural interventions are increasingly popular for treating and preventing mental health conditions. Recently, researchers have begun testing whether these interventions can effectively targeting eating disorder risk factors (disordered eating, body image concerns). This meta-analysis examined whether third-wave behavioural interventions (acceptance and commitment therapy; dialectical behaviour therapy; mindfulness-based interventions; compassion-focused therapy) show potential for being effective eating disorder prevention programs, by testing their effects on eating disorder risk factors in samples without an eating disorder. Twenty-four studies (13 randomized trials) were included. Most studies delivered selective prevention programs (i.e. participants who reported elevated risk factor). Third-wave interventions led to significant pre-post (g = 0.59; 95% CI = 0.43, 0.75) and follow-up (g = 0.83; 95% CI = 0.38, 1.28) improvements in disordered eating, and significant pre-post improvements in body image (g = 0.35; 95% CI = 0.13, 0.56). DBT-based interventions were associated with the largest effects. Third-wave interventions were also significantly more efficacious than wait-lists (g = 0.39; 95% CI = 0.09, 0.69) in reducing disordered eating, but did not differ to other interventions (g = 0.25; 95% CI = -0.06, 0.57). Preliminary evidence suggests that third-wave interventions may have a beneficial effect in ameliorating eating disorder risk.

Scrupulosity and hoarding.

OBJECTIVE: Recent evidence suggests that avoiding waste may be a prominent motive to save in hoarding disorder. Such beliefs are reminiscent of scrupulosity obsessions in OCD. This paper reports on three studies examining scrupulosity-like beliefs in hoarding and the development and validation of a measure of material scrupulosity. METHODS: Study one examined the reliability and validity of a measure of material scrupulosity (MOMS) and its relationship to hoarding in a college student sample, as well as the relationship between hoarding and OCD-base scrupulosity. Study 2 examined the psychometric properties of the MOMS in a replication of study 1 with a sample of people with hoarding problems. Study 3 examined the reliability and validity of the MOMS in a large nonclinical/community sample. RESULTS: Findings across the studies provided evidence for the reliability and validity of the MOMS. It was highly correlated with hoarding symptoms, especially difficulty discarding, and hoarding related beliefs, especially responsibility beliefs. It accounted for significant variance in hoarding symptoms independent of other correlates, including other hoarding beliefs. OCD-based scrupulosity was correlated with hoarding in sample 1, but not in the hoarding sample in study 2. CONCLUSIONS: Material Scrupulosity refers to an exaggerated sense of duty or moral/ethical responsibility for the care and disposition of possessions to prevent their being harmed or wasted. It appears to be distinct from other hoarding-related beliefs and a significant predictor of hoarding symptoms. The MOMS appears to possess good reliability and validity in both clinical and nonclinical samples.

Mindfulness-based interventions and their effects on emotional clarity: A systematic review and meta-analysis.

BACKGROUND: An inability to identify or describe internal emotional experience has been linked to a range of affective disorders. Despite burgeoning research on mindfulness-based interventions and their possible effects on emotion regulation, the effects of such interventions on emotional clarity is unclear. This review examines the evidence for the effect of mindfulness-based interventions on self-reported emotional clarity. METHOD: Published studies indexed by PsycINFO, PubMed and Scopus, as available in April 2017, were systematically reviewed. Interventions that included mindfulness practice or philosophy, and reported a suitable measure of emotional clarity at pre- and post-intervention were selected. A random-effects meta-analysis was performed. Subgroup comparisons were also conducted to test for differences between clinical and non-clinical samples, between specific and approximate measures of emotional clarity, and between controlled and uncontrolled trials. RESULTS: Seventeen studies met the criteria for inclusion. The overall estimated effect size for pre- to post-intervention was small to moderate, Hedges' g = 0.42, 95% CI [0.25, 0.59] and for between groups results was small to large, Hedges' g = 0.52, 95% CI [0.15, 0.90]. LIMITATIONS: Studies varied substantially in design quality and study characteristics. Furthermore, while interventions in the reviewed studies all had mindfulness components, many had other components in addition to mindfulness. Consequently, this review is limited by the heterogeneity of studies and results should be interpreted with caution. CONCLUSIONS: There is preliminary evidence to suggest that mindfulness-based interventions may increase emotional clarity. However, more homogenous and targeted experiments are required to confirm these initial findings.

Self-compassion moderates the perfectionism and depression link in both adolescence and adulthood.

BACKGROUND: Psychological practitioners often seek to directly change the form or frequency of clients' maladaptive perfectionist thoughts, because such thoughts predict future depression. Indirect strategies, such as self-compassion interventions, that seek to change clients' relationships to difficult thoughts, rather than trying to change the thoughts directly could be just as effective. This study aimed to investigate whether self-compassion moderated, or weakened, the relationship between high perfectionism and high depression symptoms in both adolescence and adulthood. METHODS: The present study utilised anonymous self-report questionnaires to assess maladaptive perfectionism, depression, and self-compassion across two samples covering much of the lifespan. Questionnaires were administered in a high school setting for the adolescent sample (Study 1, Mage = 14.1 years, n = 541), and advertised through university and widely online to attract a convenience sample of adults (Study 2, Mage = 25.22 years, n = 515). RESULTS: Moderation analyses revealed that self-compassion reduced the strength of relationship between maladaptive perfectionism and depression in our adolescent Study 1 (ß = -.15, p < .001, R2 = .021.) and our adult study 2 (ß = -.14, p < .001, R2 = .020). LIMITATIONS: Cross-sectional self-reported data restricts the application of causal conclusions and also relies on accurate self-awareness and willingness to respond to questionnaire openly. CONCLUSIONS: The replication of this finding in two samples and across different age-appropriate measures suggests that self-compassion does moderate the link between perfectionism and depression. Self-compassion interventions may be a useful way to undermine the effects of maladaptive perfectionism, but future experimental or intervention research is needed to fully assess this important possibility.

The cognitive-behavioural model of hoarding disorder: Evidence from clinical and non-clinical cohorts.

The cognitive-behavioural model of hoarding disorder incorporates information processing difficulties, maladaptive attachment to possessions, erroneous beliefs about the nature of possessions, and mood problems as etiologically significant factors, although developmental experiences such as a compromised early family environment have also been proposed in an augmented model. This study examined the specificity and relevance of variables highlighted in the augmented cognitive-behavioural model. Various clinical participants (n = 89) and community controls (n = 20) were assessed with structured clinical interviews to verify diagnosis. Participants completed self-report measures of hoarding severity, cognitions, meta-memory, and early developmental experiences (e.g., memories of warmth and security in one's family). Hoarding cohorts (with and without obsessive-compulsive disorder) reported poor confidence in memory, but relative to other groups (obsessive-compulsive disorder without hoarding disorder, anxiety disorders, and healthy controls), hoarding-relevant cognitions, need to keep possessions in view, and concerns about the consequences of forgetting were significantly higher. Hoarding groups reported the lowest recollections of warmth in their family, although no differences were found between hoarding and non hoarding clinical cohorts for uncertainty about self and others. Nonetheless, clinical cohorts reported generally higher scores of uncertainty than healthy controls. When predicting hoarding severity, after controlling for age and mood, recollections of lack of warmth in one's family was a significant predictor of hoarding severity, with hoarding-related cognitions and fears about decision-making being additional unique predictors. The study supports the augmented cognitive-behavioural model of hoarding, inclusive of the importance of early developmental influences in hoarding.

Emotion regulation difficulties in obsessive-compulsive disorder.

OBJECTIVE: Emotion regulation difficulties are implicated in psychological disorders but their role in obsessive-compulsive disorder (OCD) is unclear. Two studies examining these difficulties in OCD are presented. METHOD: A community sample (Study 1; n = 306) and a clinical OCD sample (Study 2; n = 59) completed the Difficulties in Emotion Regulation Scale (DERS) and measures of depression, anxiety, and OCD. In Study 2, the OCD sample was compared to a matched control group (n = 59, selected from Study 1). RESULTS: In Study 1, OCD was positively correlated with DERS total and subscale scores, and the DERS significantly predicted OCD severity even after accounting for age, gender, depression, and anxiety. In Study 2, emotion regulation difficulties were significantly higher in the clinical sample compared to the matched control group, even after accounting for depression and anxiety. CONCLUSION: Results showed that emotion regulation difficulties in OCD cannot simply be attributed to mood difficulties. Theoretical and treatment implications are discussed.

Testing the Bivalent Fear of Evaluation Model of Social Anxiety: The Relationship between Fear of Positive Evaluation, Social Anxiety, and Perfectionism.

The Bivalent Fear of Evaluation (BFOE) model of social anxiety proposes that fear of negative evaluation (FNE) and fear of positive evaluation (FPE) play distinct roles in social anxiety. Research is however lacking in terms of how FPE is related to perfectionism and how these constructs interact to predict social anxiety. Participants were 382 individuals from the general community and included an oversampling of individuals with social anxiety. Measures of FPE, FNE, perfectionism, and social anxiety were administered. Results were mostly consistent with the predictions made by the BFOE model and showed that accounting for confounding variables, FPE correlated negatively with high standards but positively with maladaptive perfectionism. FNE was also positively correlated with maladaptive perfectionism, but there was no significant relationship between FNE and high standards. Also consistent with BFOE model, both FNE and FPE significantly moderated the relationship between maladaptive perfectionism and social anxiety with the relationship strengthened at high levels of FPE and FNE. These findings provide additional support for the BFOE model and implications are discussed.

Effectiveness of an alarm intervention with overlearning for primary nocturnal enuresis.

OBJECTIVE: To explore the effectiveness of the enuresis alarm with overlearning for treatment of primary nocturnal enuresis (PNE). A key objective was to explore the effect of overlearning on treatment gains, and its impact on relapse. PATIENTS AND METHODS: The RMIT University Psychology Clinic has been treating PNE in the community for more than 20 years following a standardized treatment protocol. The study analysed archival data of 126 participants, aged ≥ 5 years, presenting with PNE. A mean wetting frequency of 5.13 wet nights per week was observed at baseline. RESULTS: Treatment significantly reduced mean wetting from baseline levels during both treatment and overlearning phases, F(1.41, 176.10) = 588.54, p < 0.001, r(2) = 0.77, 95% CI (0.74-0.81). Wet nights per week reduced from a mean of 5.13 (SD = 1.77) during baseline to 1.88 (SD = 0.85) during treatment, and 0.64 (SD = 0.60) during overlearning. Alarm treatment with overlearning produced a treatment response of 87%, compared with 59% for alarm treatment only. CONCLUSIONS: Evidence of improved treatment response with the addition of overlearning suggests overlearning should be considered as a potentially useful adjunct to alarm treatment for PNE. Overlearning was not unreasonably onerous for participants. Further research is required to explore the impact overlearning has on reducing relapse rates.

Obsessive-compulsive disorder and comorbid depression: the role of OCD-related and non-specific factors.

Although comorbid depression is a predictor of poor treatment response in obsessive-compulsive disorder (OCD), there is limited understanding of factors that contribute to depression severity in OCD. The current study examines the influence of OCD-related factors (autogenous obsessions and obsessional beliefs) and non-specific factors (avoidance and anxiety) on depression severity in a sample of OCD patients. There were 56 participants with only OCD and 46 with OCD and comorbid depression. Self-report questionnaires measuring depression, OCD-related factors, and non-specific factors were completed. Although there were no significant differences between the two groups on these variables, depression severity was positively correlated with anxiety, avoidance, obsessional beliefs, and autogenous obsessions in the whole sample. When entered into a multiple regression model to predict depression severity, these factors accounted for 51% of the variance. While OCD-related factors remained significant predictors after controlling for non-specific factors, the non-specific factors made the most significant contributions to the model. Our findings suggest that in addition to dealing with autogenous obsessions, addressing anxiety and avoidance might lead to improvements in the treatment of OCD with comorbid depression.
