Cognitive Performance as a Function of Sleep Disturbance in the Postpartum Period (open access)

Cognitive Performance as a Function of Sleep Disturbance in the Postpartum Period

New mothers often complain of impaired cognitive functioning, and it is well documented that women experience a significant increase in sleep disturbance after the birth of a child. Sleep disturbance has been linked to impaired cognitive performance in several populations, including commercial truck drivers, airline pilots, and medical residents, though this relationship has rarely been studied in postpartum women. In the present study 13 pregnant women and a group of 22 non-pregnant controls completed one week of actigraphy followed by a battery of neuropsychological tests and questionnaires in the last month of pregnancy (Time 1) and again at four weeks postpartum (Time 2). Pregnant women experienced significantly more objective and subjective sleep disturbance than the control group at both time points. They also demonstrated more impairment in objective, but not subjective cognitive functioning. Preliminary analyses indicated increased objective sleep fragmentation from Time 1 to Time 2 predicted decreased objective cognitive performance from Time 1 to Time 2, though small sample size limited the power of these findings. Implications for perinatal women and need for future research were discussed.

Universal Suicide Risk Screening in the Parkland Health and Hospital System: Evaluation of the Parkland Algorithm for Suicide Screening

Access: Use of this item is restricted to the UNT Community
Suicide is a significant public health issue in the US. Despite national and international prioritization since 1996, little definitive progress has been made in terms of identification and intervention in cases of elevated suicide risk. Forty percent of those who died by suicide attended an emergency department within a year of death. Therefore, universal suicide risk screening in emergency departments could prove a vital component to a national suicide prevention strategy. The present study empirically evaluated the universal suicide risk screening program recently implemented at Parkland Health and Hospital System. The sample consisted of patients over 18 years of age (N=333,855; Mage=42.7, 32% male) screened as part of routine clinical care from May 4th, 2015, through November 3rd, 2015. The Parkland Algorithm for Suicide Screening (PASS) is part of a clinical decision support system for responses to Columbia - Suicide Severity Rating Scale Clinical Practice Screener (C-SSRS) items, leading to an automated clinical response via three suicide risk stratification levels: no action for no risk identified, psychiatric social worker assessment for moderate risk identified, and psychiatrist/psychologist interview for high risk identified. The present study used receiver operating characteristic (ROC) curve analysis, which found the PASS predicted disposition (z=30.46, p<.001, AUC=.78, …

A Mixed Methods Approach to Exploring Social Support and Resilience in Coping with Stigma and Psychological Distress among HIV-Positive Adults (open access)

A Mixed Methods Approach to Exploring Social Support and Resilience in Coping with Stigma and Psychological Distress among HIV-Positive Adults

Since its emergence in the U.S., HIV has been a stigmatized illness. People living with HIV (PLH) are a minority and prone to psychological distress and poor mental health outcomes due to HIV-related stigma. PLH who identify with another minority group in addition to being HIV-positive (e.g., gay, African-American) experience multiple forms of oppression or layered stigma. Affirmative social support and resilience are negatively associated with HIV-stigma and are important coping resources for PLH. We used an explanatory sequential mixed methods design study involving a quantitative survey phase and a qualitative interview phase. We explored whether social support and resilience (Positive Psychological Resources) mediate or moderate the relationship between HIV Stigma and Psychological Distress among HIV-positive adults using partial least squares (PLS) path modeling and multiple regressions. Via PLS, we found Positive Psychological Resources partially mediated the relationship between HIV Stigma and Psychological Distress: the path between HIV Stigma and Psychological distress reduced (from t = 5.49, p = .000 to t = 2.39, p = .000) but remained statistically significant. Similarly, via regression, the Sobel test was significant (Sobel = .26, SE = .07, z = 3.63, p = .000). However, moderation was not found (HIV Stigma x Positive …

Forgiving the Unforgivable: Forgiveness in the Context of LGBT Partner Violence (open access)

Forgiving the Unforgivable: Forgiveness in the Context of LGBT Partner Violence

Intimate partner violence (IPV) in sexual and gender minority relationships is an underexplored and misunderstood phenomenon. Much of what has been investigated has explored IPV from a heterosexual lens, without taking into account the complexities of these relationship dynamics. Further, outcomes of IPV traditionally focus on negative sequelae, such as depression or anxiety. In this study, we examined the propensity to forgive partner abuse as a means of adaptively coping with the trauma. Further, we looked at resilience as a possible factor in the process of forgiveness. We hypothesized that psychological resilience significantly moderates the forgiveness process in sexual and gender minorities who have experienced IPV. Our sample of 77 gender- and sexual-minority participants completed measures of psychological and physical IPV, resilience, and forgiveness. A regression analysis found our model accounted for 36% of the variance in forgiveness of self (adj. R2=.36, F (4, 72) = 10.34, p < .01) and 20% of forgiveness of others (adj. R2=.20, F (4, 72) = 5.01, p < .01). However, there was no significant moderating effect, nor was IPV a significant contributor to forgiveness. Results suggest trauma does not influence one’s likelihood to forgive, though some personal trait, such as resilience, is more …
