The relationship between schizotypal traits and hoarding symptoms: An examination of symptom specificity and the role of perceived cognitive failures.

BACKGROUND: Hoarding disorder presents significant individual and interpersonal consequences. Because hoarding has only recently been added to the DSM, relatively little is known about associated comorbidity patterns. Several researchers have postulated a relationship between hoarding and schizotypy. To date, however, no investigations have considered which specific types of schizotypal traits relate to hoarding symptoms. METHODS: We examined the association between hoarding and schizotypal symptoms using multivariate analyses in two samples-a sample of 120 young adults and a community sample of 291 individuals recruited from Mechanical Turk's online crowdsourcing system. RESULTS: Individuals who fell within the clinical range on the Saving Inventory Revised endorsed significantly greater levels of schizotypal symptoms compared to those with normative saving behaviors. Odd speech, magical thinking, and social anxiety were the most consistent schizotypal correlates of hoarding symptoms. Perceived cognitive dysfunction mediated the effects between odd speech and social anxiety and hoarding symptoms, suggesting that shared abnormalities in cognitive functioning may help explain the relationship between hoarding and schizotypy. LIMITATIONS: This study examined the spectrum of schizotypy and hoarding symptoms via self-report in two nonclinical populations. CONCLUSIONS: Findings underscore the importance of assessing schizotypal traits in patients with hoarding, and suggest future avenues of research to better understand the underlying causes explaining the overlap, as well as potential treatment implications.

The mediating effect of family cohesion in reducing patient symptoms and family distress in a culturally informed family therapy for schizophrenia: A parallel-process latent-growth model.

OBJECTIVE: Although both patients with schizophrenia and their caregivers report elevated levels of depression, anxiety, and stress (DASS), affective symptoms in patients and family members seldom constitute a primary treatment focus. The present study tested whether a culturally informed family therapy for schizophrenia (CIT-S) outperformed standard family psychoeducation (PSY-ED) not only in decreasing patient schizophrenia symptoms, but also in decreasing individual DASS. Because CIT-S fostered family cohesion throughout treatment, we predicted that increases in family cohesion would mediate treatment effects. METHOD: Participants included 266 patients and family members nested within 115 families, randomized to the CIT-S or PSY-ED conditions. We specified a series of multilevel latent growth and latent change models to examine direct effects of CIT-S on patient schizophrenia symptoms, individual DASS, and family cohesion over time. Next, we used parallel-process growth models to test the indirect effect of CIT-S on decreasing patient and caregiver psychopathology over time via changes in family cohesion. RESULTS: The CIT-S treatment significantly reduced patient schizophrenia symptoms from baseline to follow-up (γ = -1.72, 95% confidence interval [CI] [-2.83, -0.60]), as well as individual DASS (γ = -4.39, 95% CI [-6.44, -2.34]) from baseline to termination. In line with treatment goals, CIT-S increased family cohesion from baseline to midpoint (γ = 0.93, 95% CI [0.06, 1.80]). The CIT-S-related change in cohesion mediated changes in DASS (γ = -0.87, 95% CI [-1.47, -0.27]), but not patient symptoms. CONCLUSION: By integrating the family's cultural context into treatment, clinicians may foster family dynamics that enhance treatment outcomes and promote broad improvements in mental health.

Stigma, Expressed Emotion, and Quality of Life in Caregivers of Individuals with Dementia.

Expressed emotion (EE) is a measure of a caregiver's critical and emotionally overinvolved (EOI; e.g., intrusive, self-sacrificing) attitudes and behaviors toward a person with a mental illness. Mounting evidence indicates that high levels of these critical and EOI attitudes and behaviors (collectively termed high EE) in family members are associated with a poorer course of illness for people with a range of disorders, including dementia (Nomura et al., 2005). However, less is known about factors that might trigger high EE and how high EE might impact dementia caregivers' own mental health. In this study we propose that caregivers who perceive stigma from their relative's illness may be more likely to be critical or intrusive (high EOI) toward their relative in an attempt to control symptomatic behaviors. We further hypothesized that high EE would partially mediate the link between stigma and quality of life (QoL) as there is some evidence that high EE is associated with poorer mental health in caregivers themselves (Safavi et al., 2015). In line with study hypotheses and using a sample of 106 dementia caregivers, we found that greater caregiver stigma was associated with both high EE (for criticism and EOI) and with poorer QoL. Mediational analyses further confirmed that high EE accounts for much of the association between stigma and poorer QoL. Study results suggest that addressing caregiver stigma in therapy could reduce levels of high EE and indirectly therefore improve caregiver QoL. Intervening directly to reduce high EE could also improve caregiver QoL.

Acculturation styles and their associations with psychiatric symptoms and quality of life in ethnic minorities with schizophrenia.

This study examined whether Berry's model of acculturative stress would predict psychiatric symptom severity and quality of life (QoL) in ethnic minorities with schizophrenia. Tested extensively in non-psychiatric populations, Berry's framework generally suggests that integration, or engagement with both the host and minority culture, is most adaptive. Using the Abbreviated Multidimensional Acculturation Scale (AMAS), we tested the hypothesis that individuals with schizophrenia who employed an integrative acculturation strategy would have the highest QoL and lowest symptom severity, followed by the assimilation and enculturation groups, then the marginalized group. Psychiatric symptoms and QoL were regressed on AMAS assimilation scores, enculturation scores, and the interaction term in a sample of 128 Hispanic and Blacks with schizophrenia (M age = 41.28; 70% male). Acculturation strategy was not found to relate to psychiatric symptoms (measured from the Brief Psychiatric Rating Scale). However, acculturation strategy did predict QoL (measured from the Quality of Life Inventory), and results were in line with Berry's model. Marginalization may exacerbate issues surrounding social identity in schizophrenia, including low self-concept clarity and internalized stigma. Encouraging bicultural individuals with schizophrenia to interact with the host culture while also practicing traditions from their minority culture may help improve their quality of life.

The Reciprocal Influence of Callous-Unemotional Traits, Oppositional Defiant Disorder and Parenting Practices in Preschoolers.

The present study investigates reciprocal associations between positive parenting, parental monitoring, CU traits, and ODD in children assessed at age 3 and again at age 6. Data were collected from a sample of preschoolers (N = 419; 51.58 % female) through diagnostic interviews and questionnaires answered by parents and teachers. Structural equation modeling revealed a bidirectional relationship between poor monitoring and ODD, with poor monitoring at age 3 predicting ODD at age 6 (ß = 0.11, p < 0.05), and ODD at age 3 predicting poor monitoring at age 6 (ß = 0.10, p < 0.05). While poor monitoring at age 3 predicted CU traits at age 6 (ß = 0.11, p < 0.05), CU traits at age 3 predicted positive parenting (ß = 0.09, p < 0.05) and ODD (ß = 0.13, p < 0.05) at age 6. Results have important implications for early targeted parenting interventions for CU traits and ODD.

Is executive cognitive function associated with youth gambling?

Our objectives for this report were to identify trajectories of youth gambling behavior, and to examine their relation to executive cognitive function (ECF) and associated problem behaviors. Philadelphia school children, enrolled at ages 10-12 years (n = 387; 49% male), completed three annual assessments of risk behaviors, ECF, impulsivity, problem behaviors and demographics. Across ages 10-15 years, using methods from Nagin et al., two groups were identified: Early Gamblers (n = 111) initiated early and continued in later assessments, and Later Gamblers (n = 276) initiated at later ages and gambled less. Betting money on cards and sports were the most frequently reported gambling behaviors. Using gambling group as outcome, final backward selection logistic regression model showed Early Gamblers are more likely male (P = 0.001), report more active coping (P = 0.042), impulsive behaviors (P ≤ 0.008), and have friends who gamble (P = 0.001). Groups were similar in ECF, parental monitoring, marital status, SES, and race. Early Gamblers had higher incidence of problem behaviors and drug use (all P ≤ 0.006). Two gambling groups were identified in early adolescence with Early Gamblers showing higher levels of impulsivity and comorbid problems but similar levels of ECF compared to Late Gamblers. As more gambling groups are identified through later adolescence, ECF may emerge as a relevant precursor of problem gambling at this later time.
