Structural equation modeling was used to test hypotheses. Results from an independent genome-wide association study of 5-hydroxyindoleacetic acid in the cerebrospinal fluid were used to create serotonin (5-HT) polygenic risk scores, wherein higher scores reflected lower levels of 5-HT functioning. Data from three time points were drawn from each sample, and all paths were prospective. Findings suggested that 5-HT polygenic risk did not predict self-regulatory constructs. However, 5-HT polygenic risk did predict the divergent outcomes of depression and aggression/antisociality, such that higher levels of 5-HT polygenic risk predicted greater levels of depression and aggression/antisociality. Results most clearly supported adolescents’ aggression/antisociality as a mechanism in the relation between 5-HT polygenic risk and later alcohol use. Deficits in self-regulation also predicted depression and aggression/antisociality, and indirectly predicted alcohol use through aggression/antisociality. These pathways to alcohol use might be the most salient for boys with low levels of socioeconomic status.
Results are novel contributions to the literature. The previously observed association between serotonin functioning and alcohol use might be due, in part, to the fact that individuals with lower levels of serotonin functioning are predisposed towards developing earlier aggression/antisociality. Results did not support the hypothesis that serotonin functioning predisposes individuals to deficits in self-regulatory abilities. Findings extend previous research by suggesting that serotonin functioning and self-regulation might be transdiagnostic risk factors for many types of psychopathology.
another culture) lessened the positive link between depression and alcohol use quantity and frequency. Those with higher levels of acculturation reported less symptoms of depression and alcohol use. Enculturation (i.e., the process of immersion to one’s own ethnic culture) increased the positive link between depression and alcohol quantity and frequency. Implications for culturally competent counseling for this underserved and understudied population are discussed.
Participants included 200 parent caregivers of a child with a chronic illness. Participants responded to an online survey that measured demographics, role overload (Role Overload scale), role strain (The Revised Caregiver Burden Measure), instrumental support and social support (Medical Outcomes Survey), positive attitudes about caregiving (Brief Assessment Scale for Caregivers), depression (Patient Health Questionnaire-9), and anxiety (Generalized Anxiety Disorder scale-7). Pearson correlations and six hierarchical regression models were tested to examine caregiving stress, resources, and psychological outcomes.
Consistent with the study hypotheses, positive correlations between caregiving stress (role overload and role strain) and depression and anxiety were found. Negative correlations were found between resources (instrumental support, social support, positive attitudes) and depression and anxiety. Both instrumental support and social support had negative moderating effects on the relations between role overload and psychological outcomes (depression and anxiety). Positive attitudes also negatively moderated the relations between role strain and psychological outcomes. Thus, when participants reported high instrumental and social support, they also reported low depression and anxiety, even when role overload was high. Participants also reported low anxiety and depression when they reported high positive attitudes, even when role strain was high. Implications of these findings are discussed.
Homeless individuals encounter barriers such as lack of health insurance, increased cost of care and unavailability of resources. They have increased risk of comorbid physical disease and poor mental health. Depression is a prevalent mental health disorder in the US linked to increased risk of mortality. Literature suggests depression screening can identify high-risk individuals with using the patient health questionnaire (PHQ-9).
The objective of this project is to determine if screening identifies depression in the homeless and how it impacts healthcare access. Setting is a local organization in Phoenix offering shelter to homeless individuals. An evidence-based project was implemented over two months in 2019 using convenience sampling. Intervention included depression screening using the PHQ-9, referring to primary care and tracking appointment times. IRB approval obtained from Arizona State University, privacy discussed, and consent obtained prior to data collection. Participants were assigned a random number to protect privacy.
A chart audit tool was used to obtain sociodemographics and insurance status. Descriptive statistics used and analyzed using Intellectus. Sample size was (n = 18), age (M = 35) most were White-non-Hispanic, 44% had a high school diploma and 78% were insured. Mean score was 7.72, three were previously diagnosed and not referred. Three were referred with a turnaround appointment time of one, two and seven days respectively. No significant correlation found between age and depression severity. A significant correlation found between previous diagnosis and depression severity. Attention to PHQ-9 varied among providers and not always addressed. Future projects should focus on improving collaboration between this facility and providers, increasing screening and ensuring adequate follow up and treatment.
