Visually mediated functioning improves following treatment of hoarding disorder.

BACKGROUND: Hoarding disorder (HD) is a highly debilitating psychiatric disorder that affects 2-6% of adults. Neuropsychological deficits in visual memory, detection, and categorization have been reported in HD. To date, no study has examined the relationship between neurocognitive functioning and treatment for HD. We aim to determine the association between neurocognitive functioning and treatment outcomes, as well as the impact of HD-specific treatment on cognitive functioning. METHODS: 323 individuals with HD were randomized to 20 weeks of peer- or clinician-led group behavioral treatment. 242 participants completed pre- and post-treatment neuropsychological testing covering eight neurocognitive domains. Rates of cognitive impairment (CI) were assessed for each neurocognitive domain. The association of baseline neurocognitive function on treatment response was examined using multiple regression. MANOVA and post-hoc tests were used to determine neurocognitive performance change pre- to post treatment. RESULTS: Sixty-seven percent of participants had CI on ≥1 cognitive domain. There was no significant effect of pre-treatment neurocognitive functioning on treatment outcome. Post-treatment improvements were observed in visual memory, visual detection, decision making, information processing speed, visuospatial processing, attention/working memory (p≤.001). Declines in performance were found in visual reaction time and categorization. LIMITATIONS: This was a non-inferiority trial to examine two treatment types with no normative comparison group. Treatment seeking individuals are more likely to be insightful, motivated, and have other features which limit generalizability. CONCLUSIONS: Patterns of cognitive impairment in HD are similar to previous reports. Pre-treatment neurocognitive functioning did not impact treatment response. Neuropsychological functioning improved across multiple domains following targeted treatment.

Predicting Nursing Program Success for Veterans: Examining the Importance of TEAS and Pre-Admit Science GPA.

BACKGROUND: Support for veterans in nursing education programs is a priority in universities across the U.S. While studies have examined the relationship between admission criteria and successful nursing program outcomes, minimal data are available regarding predictors of veteran student success. METHODS: Success for veterans in one university BSN nursing program was examined, as measured by three outcomes: Nursing program graduation GPA, graduation rate, and NCLEX-RN pass rate, as predicted by two admission criteria: GPA and TEAS. RESULTS: Among veteran students, pre-admit science GPAs at or above the median score (3.41) predicted higher nursing program graduation GPA, but did not predict graduation rates or NCLEX-RN pass rates. TEAS scores were not predictive of nursing program graduation GPA, graduation rates or NCLEX-RN pass rates. In comparison, veteran and non-veteran nursing students' graduation rates and NCLEX-RN pass rates were similar; with average nursing program graduation GPAs slightly lower for veterans. Veterans contributed gender, age, and cultural diversity to the nursing student body. When NCLEX-RN exam retakes are included, 100% of all veteran participants were successful, a possible indicator of resilience and work ethic. CONCLUSION: Further discussion is indicated regarding nursing program admission criteria, and factors for success of veterans in nursing programs.

Recruiting under-represented populations into psychiatric research: Results from the help for hoarding study.

This study compares the effectiveness of approaches used to recruit a diverse sample for a randomized clinical trial for Hoarding Disorder (HD) in the San Francisco Bay Area. Of the 632 individuals who inquired about the study, 313 were randomized and 231 completed treatment. Most participants heard about the study via flyering (N = 161), followed by advocacy groups (N = 113), word of mouth (N = 84), health care professionals (N = 78), online (N = 68), and media (N = 11). However, those that heard about the study via advertising methods, such as flyers, were less likely to complete the study, p = .01, while those recruited via advocacy groups were most likely to be randomized, p = .03. No source proved more effective in recruiting underrepresented groups such as men, p = .60; non-whites, p = .49; or Hispanics, p = .97. Advertising recruited the youngest individuals, p < 0.001, and word of mouth was most likely to recruit unemployed, disabled, or retired individuals, p = .01. Thus, results suggest an ongoing multimodal approach is likely to be most effective in both soliciting and retaining a diverse sample. Future studies should compare recruitment methods across greater geographical regions too, as well as in terms of financial and human costs.

Randomised clinical trial of community-based peer-led and psychologist-led group treatment for hoarding disorder.

BACKGROUND: Treatment for hoarding disorder is typically performed by mental health professionals, potentially limiting access to care in underserved areas. AIMS: We aimed to conduct a non-inferiority trial of group peer-facilitated therapy (G-PFT) and group psychologist-led cognitive-behavioural therapy (G-CBT). METHOD: We randomised 323 adults with hording disorder 15 weeks of G-PFT or 16 weeks of G-CBT and assessed at baseline, post-treatment and longitudinally (≥3 months post-treatment: mean 14.4 months, range 3-25). Predictors of treatment response were examined. RESULTS: G-PFT (effect size 1.20) was as effective as G-CBT (effect size 1.21; between-group difference 1.82 points, t = -1.71, d.f. = 245, P = 0.04). More homework completion and ongoing help from family and friends resulted in lower severity scores at longitudinal follow-up (t = 2.79, d.f. = 175, P = 0.006; t = 2.89, d.f. = 175, P = 0.004). CONCLUSIONS: Peer-led groups were as effective as psychologist-led groups, providing a novel treatment avenue for individuals without access to mental health professionals.

Contributions of self-criticism and shame to hoarding.

Pathological hoarding-related beliefs, such as need to control possessions, and inflated sense of responsibility over possessions, have been used to explain the development of symptoms of hoarding disorder (HD). While these beliefs have been the focus of the current standard treatment for HD, it is of significant clinical interest to further examine other constructs that may be linked to, or may underliethese beliefs, as well as the pathology of HD. To this end, the current study aimed to build on existing findings regarding the relationship of compromised self-identity with HD. Specifically, we investigated the relationship between self-criticism, shame, hoarding beliefs, and severity of HD symptoms among 104 treatment-seeking individuals with HD. We found that self-criticism and shame are positively associated with HD symptoms and hoarding related beliefs. Moreover, our data shed light on how these factors are connected by elucidating the indirect effects of self-criticism and shame on HD symptoms, mediated through beliefs about inflated sense of responsibility over possessions. The findings have implications for future research to examine interventions targeting compromised self-identity, including self-criticism and shame, among individuals with HD.

Examining the Importance of Admissions Criteria in Predicting Nursing Program Success.

Baccalaureate nursing programs select students likely to graduate, become licensed, and contribute to a diverse workforce, and admissions criteria need to support those goals. This study assessed five criteria: pre-admit science GPA; TEAS score; healthcare experience; previous baccalaureate degree; and pre-admission university enrollment vs. college transfer as predictors of three desired outcomes: graduation; nursing program GPA; and passing NCLEX-RN. Results found TEAS and pre-admit science GPA predicted nursing program outcomes. Students with TEAS≥82 had 8 % greater probability of graduating, 13 % greater probability of a GPA≥3.25, and 9 % greater probability of passing NCLEX-RN, compared to students with TEAS < 82. Students with pre-admit science GPAs≥3.8 had 11 % greater probability of passing NCLEX-RN and 14 % greater probability of a GPA≥3.25 compared to students with pre-admit science GPAs < 3.8. Further discussions regarding factors important for training a diverse nursing workforce and effective ways to implement non-academic admission criteria are warranted.

Comparison of a peer facilitated support group to cognitive behavior therapy: Study protocol for a randomized controlled trial for hoarding disorder.

Although individual and group cognitive-behavioral therapy (CBT) is the standard treatment approach for hoarding disorder (HD), it requires trained mental health professionals with specialization in HD. There is a need to offer additional options and services due to the limited number of professionals with advanced training, combined with the high prevalence rate of individuals with HD. A structured support group led by trained facilitators or lay professionals using a facilitator's manual and participant workbook (Buried in Treasures or BiT), addresses this need and increases accessibility. Prior studies of BiT groups have shown decreased hoarding symptoms. Only one retrospective study compared BiT and CBT outcomes in a naturalistic setting and showed no difference. Thus, a well-powered randomized controlled trial is needed to directly compare these forms of treatment. This paper presents a non-inferiority controlled trial protocol that compares group CBT to group BiT. Three hundred participants with HD, 18years or older, are being recruited for a 16-week treatment study. Participants are randomly assigned to either the CBT or BiT group. The primary outcome is reduction in hoarding symptom severity. Secondary outcomes include reduction in other indices of hoarding symptomology, including functional impairment, physical clutter, cognition, and changes in neuropsychological functioning.

Web-based phenotyping for Tourette Syndrome: Reliability of common co-morbid diagnoses.

Collecting phenotypic data necessary for genetic analyses of neuropsychiatric disorders is time consuming and costly. Development of web-based phenotype assessments would greatly improve the efficiency and cost-effectiveness of genetic research. However, evaluating the reliability of this approach compared to standard, in-depth clinical interviews is essential. The current study replicates and extends a preliminary report on the utility of a web-based screen for Tourette Syndrome (TS) and common comorbid diagnoses (obsessive compulsive disorder (OCD) and attention deficit/hyperactivity disorder (ADHD)). A subset of individuals who completed a web-based phenotyping assessment for a TS genetic study was invited to participate in semi-structured diagnostic clinical interviews. The data from these interviews were used to determine participants' diagnostic status for TS, OCD, and ADHD using best estimate procedures, which then served as the gold standard to compare diagnoses assigned using web-based screen data. The results show high rates of agreement for TS. Kappas for OCD and ADHD diagnoses were also high and together demonstrate the utility of this self-report data in comparison previous diagnoses from clinicians and dimensional assessment methods.

The synergistic effect of growing older with hoarding behaviors.

Clinically significant hoarding behaviors (HB) have been defined as acquisition of, and failure to discard, large numbers of items, which limits the use of one's home and causes functional impairment or distress. HB disproportionally affect adults aged 55 and older, and although research on HB has accelerated in the past decade, few studies focus on older adults. This qualitative study, based on grounded theory methodology, utilized interview data from 22 older adults with HB to understand the dynamic interaction between HB and the aging process. Participants described the specific ways that their chronic HB were complicated by changes in their health status, social context, and home setting, resulting in greater functional impairment and distress. By identifying these changes that commonly occur with age and their synergistic relationship with HB, nurses and other health professionals can develop targeted interventions to improve home safety and support the independence of these older adults.
