RESUMEN

BACKGROUND: Prior studies indicate that neuroactive steroids mediate some of alcohol's effects. Dutasteride, widely used to treat benign prostatic hypertrophy, is an inhibitor of 5-alpha reductase enzymes, which play a central role in the production of 5α-reduced neuroactive steroids. The purpose of this study was to test dutasteride's tolerability and efficacy for reducing drinking. METHODS: Men (n = 142) with heavy drinking (>24 drinks per week) and a goal to either stop or reduce drinking to nonhazardous levels were randomized to placebo or 1 mg dutasteride daily for 12 weeks. We hypothesized that dutasteride-treated patients would be more successful in reducing drinking. RESULTS: Generalized linear mixed models that included baseline drinking, treatment, time and their 2-way interaction identified significant interactions of treatment-time, such that dutasteride treatment reduced drinking more than placebo. During the last month of treatment, 25% of dutasteride-treated participants had no hazardous drinking (no heavy drinking days and not more than 14 drinks per week) compared with 6% of placebo-treated participants (P = 0.006; NNT = 6). Sensitivity analysis identified baseline drinking to cope as a factor associated with larger reductions in drinking for dutasteride compared with placebo-treated participants. Dutasteride was well tolerated. Adverse events more common in the dutasteride group were stomach discomfort and reduced libido. CONCLUSION: Dutasteride 1 mg daily was efficacious in reducing the number of heavy drinking days and drinks per week in treatment-seeking men. The benefit of dutasteride compared with placebo was greatest for participants with elevated baseline drinking to cope motives.

RESUMEN

INTRODUCTION: Cognitive dysfunction or deficits are common in patients with major depressive disorder (MDD). The current study systematically reviews and meta-analyzes multiple domains of cognitive impairment in patients with MDD. METHODS: PubMed/MEDLINE, PsycINFO, Cochrane Library, Embase, Web of Science, and Google Scholar were searched from inception through May 17, 2023, with no language limits. Studies with the following inclusion criteria were included: (1) patients with a diagnosis of MDD using standardized diagnostic criteria; (2) healthy controls (i.e., those without MDD); (3) neuropsychological assessments of cognitive impairment using Cambridge Neuropsychological Test Automated Battery (CANTAB); and (4) reports of sufficient data to quantify standardized effect sizes. Hedges' g standardized mean differences (SMDs) with corresponding 95% confidence intervals (CIs) were used to quantify effect sizes of cognitive impairments in MDD. SMDs were estimated using a fixed- or random-effects models. RESULTS: Overall, 33 studies consisting of 2,596 subjects (n = 1,337 for patients with MDD and n = 1,259 for healthy controls) were included. Patients with MDD, when compared to healthy controls, had moderate cognitive deficits (SMD, -0.39 [95% CI, -0.47 to -0.31]). In our subgroup analyses, patients with treatment-resistant depression (SMD, -0.56 [95% CI, -0.78 to -0.34]) and older adults with MDD (SMD, -0.51 [95% CI, -0.66 to -0.36]) had greater cognitive deficits than healthy controls. The effect size was small among unmedicated patients with MDD (SMD, -0.19 [95% CI, -0.37 to -0.00]), and we did not find any statistical difference among children. Cognitive deficits were consistently found in all domains, except the reaction time. No publication bias was reported. CONCLUSION: Because cognitive impairment in MDD can persist in remission or increase the risk of major neurodegenerative disorders, remediation of cognitive impairment in addition to alleviation of depressive symptoms should be an important goal when treating patients with MDD.

RESUMEN

Background: Recent evidence indicates that alcohol and other substance co-use, compared to alcohol-only use, might be more closely associated with negative reinforcement processes, and thus more likely during periods of increased stress. The present study examined this possibility by using data from an intensive longitudinal (daily) study of college student drinkers (N = 1461, 54% women). We also examined individual differences in coping and enhancement drinking motives as predictors of alcohol and other substance co-use. Results: We used multilevel multinomial logistic regression to predict, relative to alcohol-only days, the likelihood of alcohol co-use with either cigarettes or marijuana, along with alcohol use with multiple substances and other substance-only use from daily interpersonal and academic stress, day-of-the-week, sex, and individual differences in coping and enhancement drinking motives. We found that, relative to alcohol-only, alcohol and marijuana co-use was more likely, and non-alcohol related substance use was less likely, on weekends. Alcohol and marijuana co-use was less likely, and other substance-only use was more likely, on days characterized by greater academic stress, whereas alcohol and cigarette co-use was more likely on days characterized by greater interpersonal stress. Individuals with higher levels of drinking to cope motivation were more likely to engage in alcohol and cigarette co-use, other substance-only use, and alcohol plus multiple substances, relative to alcohol-only. Individuals with higher levels of enhancement motives were more likely to engage in all types of alcohol and other substance co-use and other substance-only use relative to alcohol-only. Conclusions: Findings are discussed in terms of the complex nature of different patterns of co-use patterns when evaluating indicators of positive- and negative-reinforcement processes.

RESUMEN

Women who have experienced intimate partner violence (IPV) are disproportionately likely to engage in sexual risk behavior, including sex with a secondary partner (i.e., sex partners outside their primary relationship). Social disconnection has been identified as a social determinant of health that may enhance understanding of sex with a secondary partner. This study extends past research by using an intensive longitudinal design consisting of multiple daily assessments to examine event-level associations between women IPV survivors' social disconnection and sex with a secondary partner concurrently (i.e., during the same aggregated assessment) and temporally (i.e., social disconnection during one assessment predicting sex with a secondary partner in a subsequent assessment) over a 14-day period, in consideration of physical, psychological, and sexual IPV, and alcohol and drug use. Participants (N = 244) were recruited from New England through 2017. Results from multilevel logistic regression models indicate that women who experienced greater social disconnection on average were more likely to report sex with a secondary partner. However, after including IPV and substance use in the model, the strength of this relationship was attenuated. Sexual IPV emerged as a between-person predictor of sex with a secondary partner in temporally lagged models. Results provide insight into the relationships between daily social disconnection and sex with a secondary partner among IPV survivors, particularly regarding the effects of substance use and IPV both concurrently and temporally. Taken together, findings emphasize the importance of social connection for women's well-being and highlight the need for interventions that enhance interpersonal connectedness.

RESUMEN

Background: To examine whether individual differences in intensive longitudinal data-derived affective dynamics (i.e. positive and negative affect variability and inertia and positive affect-negative affect bipolarity) - posited to be indicative of emotion dysregulation - are uniquely related to drinking level and affect-regulation drinking motives after controlling for mean levels of affective states. Method: We used a large sample of college student drinkers (N = 1640, 54% women) who reported on their affective states, drinking levels and drinking motives daily for 30 days using a web-based daily diary. We then calculated from the daily data positive and negative affect variability, inertia, affect bipolarity and mean levels of affect and used these as predictors of average drinking level and affect-regulation drinking motives (assessed using both retrospective and daily reporting methods). Results: Findings from dynamic structural equation models indicated that mean levels of affect were uniquely related to drinking motives, but not drinking level. Few dynamic affect predictors were uniquely related to outcomes in the predicted direction after controlling for mean affect levels. Conclusion: Our results add to the inconsistent literature regarding the associations between affective dynamics and alcohol-related outcomes, suggesting that any effects of these indicators, after controlling for mean affect levels, might be more complex than can be detected with simple linear models.

RESUMEN

OBJECTIVE: This study examined the dynamic, real-time associations between partner involvement in diabetes self-care and continuous glucose monitor (CGM) metrics in adults with type 2 diabetes. METHODS: For 1 week, 63 participants wore Dexcom G4 CGMs and provided momentary reports of partner involvement in diabetes self-care five times per day. Dynamic structural equation models were used to estimate the reciprocal lagged effects of partner involvement on next-hour CGM metrics (and vice versa). RESULTS: Partner involvement predicted improved next-hour glucose control for five of six CGM metrics in analyses adjusted for time-varying covariates. The hour after partner involvement, the model predicted a 26.34 mg/dl decrease in glucose level (standardized ß = -0.19), 30% greater odds of meeting target time in target range ( ß = 0.07), 48% higher odds of target time below target range (TBR; ß = 0.04; the only nonsignificant effect), 47% greater odds of target time above target range (ß = 0.11), a 4.20 unit decrease in glucose standard deviation ( ß = -0.19), and a 0.01 unit decrease in glucose coefficient of variation ( ß = -0.08; all p values < .05). There was less consistent support for the reverse pathway, with only two metrics significantly related to next-hour partner involvement: glucose level ( ß = 0.15) and TBR ( ß = 0.21), such that having higher levels and meeting target TBR were significantly predictive of next-hour partner involvement. CONCLUSIONS: This is the first study showing that partner involvement in daily diabetes management predicts short-term glucose control. More research is needed to understand how partners influence glycemic control and evaluate interventions that promote their involvement in diabetes care.

RESUMEN

OBJECTIVE: Systemic inflammation is commonly observed in idiopathic chronic pain conditions, including temporomandibular joint disorder (TMD). Trait positive affect (PA) is associated with lower inflammation in healthy controls, but those effects may be threatened by poor sleep. The associations between PA with proinflammatory cytokine activity and potential moderation by sleep in chronic pain are not known. We thus investigated the association between PA and circulating interleukin-6 (IL-6) and moderation of that association by sleep in a sample of women with TMD and sleep difficulties. METHODS: Participants (n = 110) completed the insomnia severity index and provided blood samples at five intervals throughout an evoked pain testing session. They then completed a 14-day diary assessing sleep and affect, along with wrist actigraphy. RESULTS: There was not a significant main effect of PA on resting or pain-evoked IL-6 (b = 0.04, p = .33). Diary total sleep time (b = -0.002, p = .008), sleep efficiency (b = -0.01, p = .005), sleep onset latency (b = 0.006, p = .010), and wake after sleep onset (b = 0.003, p = .033) interacted with PA to predict IL-6, such that PA inversely predicted IL-6 at higher levels of total sleep time and sleep efficiency and at lower levels of sleep onset latency and wake after sleep onset. Surprisingly, when sleep was poor, PA predicted greater IL-6. CONCLUSIONS: The potential salutary effects of PA on resting IL-6 erode when sleep is poor, underscoring the importance of considering sleep in conceptual and intervention models of TMD.

RESUMEN

BACKGROUND: Spouses often attempt to influence patients' diabetes self-care. Spousal influence has been linked to beneficial health outcomes in some studies, but to negative outcomes in others. PURPOSE: We aimed to clarify the conditions under which spousal influence impedes glycemic control in patients with type 2 diabetes. Spousal influence was hypothesized to associate with poorer glycemic control among patients with high diabetes distress and low relationship quality. METHODS: Patients with type 2 diabetes and their spouses (N = 63 couples) completed self-report measures before patients initiated a 7-day period of continuous glucose monitoring. Mean glucose level and coefficient of variation (CV) were regressed on spousal influence, diabetes distress, relationship quality, and their two- and three-way interactions. RESULTS: The three-way interaction significantly predicted glucose variability, but not mean level. Results revealed a cross-over interaction between spousal influence and diabetes distress at high (but not low) levels of relationship quality, such that spousal influence was associated with less variability among patients with low distress, but more among those with high distress. Among patients with high distress and low relationship quality, a 1 SD increase in spousal influence predicted a difference roughly equivalent to the difference between the sample mean CV and a CV in the unstable glycemia range. CONCLUSIONS: This was the first study to examine moderators of the link between spousal influence and glycemic control in diabetes. A large effect was found for glucose variability, but not mean levels. These novel results highlight the importance of intimate relationships in diabetes management.

RESUMEN

This study examined whether daily stressors and continuously monitored glucose levels and glucose variability predict daily diabetes symptoms. Fifty Latinos with type 2 diabetes were randomized to either diabetes education (DE-only; N = 23) or DE plus stress management and relaxation training (DE + SMR; N = 32). After treatment, for 7 days they wore 'blinded' continuous glucose monitors and reported common stressors and diabetes symptoms twice daily. Between individuals, participants with more numerous overall stressors and more time in hyperglycemia reported higher symptoms. Within individuals, symptoms were higher during intervals of greater than usual stressors. Yet, diabetes symptoms did not covary with changes in glucose levels or glucose variability. The within-person stressor-symptom association was stronger among older individuals and non-significant for participants in DE + SMR condition. Diabetes symptoms were associated with recent stressor exposure, but not recent glucose level or changes in glucose. CLINICAL TRIAL NUMBER: ClinicalTrials.gov Identifier (No. NCT01578096).

RESUMEN

OBJECTIVE: Post-traumatic growth typically refers to enduring positive psychological change experienced as a result of adversity, trauma, or highly challenging life circumstances. Critics have challenged insights from much of the prior research on this topic, pinpointing its significant methodological limitations. In response to these critiques, we propose that post-traumatic growth can be more accurately captured in terms of personality change-an approach that affords a more rigorous examination of the phenomenon. METHOD: We outline a set of conceptual and methodological questions and considerations for future work on the topic of post-traumatic growth. RESULTS: We provide a series of recommendations for researchers from across the disciplines of clinical/counseling, developmental, health, personality, and social psychology and beyond, who are interested in improving the quality of research examining resilience and growth in the context of adversity. CONCLUSION: We are hopeful that these recommendations will pave the way for a more accurate understanding of the ubiquity, durability, and causal processes underlying post-traumatic growth.

RESUMEN

Background: One-third of women who experience intimate partner violence (IPV) are identified as having alcohol use problems. Yet, little research has examined factors that may increase the risk of alcohol use among this high-risk population. Objectives: This study overcomes limitations of previous research by using micro-longitudinal methods to examine how fluctuations in PTSD symptoms throughout the day are associated with proximal drinking behavior and whether these associations are related to individuals' overall PTSD severity and race/ethnicity. Methods: Using phone-based interactive voice response, 244 female victims of current IPV reported their PTSD symptoms and drinking four times daily for 14 days. Results: Results indicated positive associations between PTSD symptom cluster severity and drinking level at the person, daily and within-day levels. The effects of within-person fluctuations in daily levels of PTSD severity on levels of drinking were stronger for individuals with lower PTSD severity. No evidence was found for within-person differences on time-lagged effects of PTSD on drinking or by racial/ethnic group. Further, in time-lagged models no evidence was found for reverse causation whereby alcohol use predicts increased PTSD symptom severity. Conclusions: Findings suggest that IPV-exposed women use alcohol to alleviate their PTSD symptoms at the micro-process level and that prevention and treatment efforts targeting PTSD symptoms may be useful in reducing alcohol use in this population. Further, these efforts should consider the overall severity of PTSD symptoms experienced given the differential findings among women with higher vs. lower PTSD symptom severity.

RESUMEN

The structure and psychometrics of daily self-report measures have only rarely been empirically tested. We developed the Daily Self-Report of Trauma-Related Sequelae (DSR-TRS), comprised of items assessing, in the past day: (1) posttraumatic stress disorder (PTSD) symptoms: (2) symptoms of affective-, behavioral-, relational-, somatic-, dissociative-, and self-dysregulation; and (3) stressors, mood, coping strategies, and drug and alcohol use. Psychometric analyses were conducted with data from 141 women who participated in a randomized clinical trial of two present-centered therapies for PTSD or a wait-list condition and completed at least one DSR-TRS during two 30-day periods at baseline and posttreatment/wait-list. Five DSR-TRS subscales were created based on a series of exploratory, confirmatory, and multilevel factor analyses: Positive Affect, Negative Affect, Self-Regulation, Dysregulation, and PTSD symptoms. DSR-TRS subscales had acceptable within-person and between-person reliability. Convergent and discriminant validity were supported at baseline and posttest in relation to questionnaire and interview assessment measures. Implications for research on daily self-report measures such as the DSR-TRS with trauma survivors are discussed.

RESUMEN

The daily emotional experiences of adolescents are dynamic, vary significantly across individuals, and are crucial to their psychological adjustment, warranting a need to identify factors that promote adaptive affective responses to stressors and attenuated affective instability. The objective of this study, therefore, was to examine protective factors linked to individual differences in daily affective reactivity and instability utilizing a daily diary design in a national sample of 100 U.S. adolescents (13-17 years; 40% girls; 79% White). Adolescents completed a baseline survey and then 14 daily online surveys. Better mother-adolescent communication predicted lower negative affect reactivity, whereas greater use of problem-focused coping strategies predicted higher positive affect reactivity. Greater trait resilience and instrumental support seeking predicted lower negative affect instability. Conversely, more emotional support seeking predicted higher negative affect instability. No factors were associated with positive affect instability, and father-adolescent communication was unrelated to daily affective reactivity and instability. The findings implicate specific protective factors associated with distinct aspects of affective reactivity and instability.

RESUMEN

This pilot randomized clinical trial tested an emotion regulation enhancement to Cognitive Behavior Therapy (CBT) with 29 college student problem drinkers with histories of complex trauma and current clinically significant traumatic stress symptoms. Participants received eight face-to-face sessions of manualized internet-supported CBT for problem drinking with or without trauma-focused emotion regulation skills (Trauma Affect Regulation: Guide for Education and Therapy, TARGET). Both interventions were associated with sustained (at one-month follow-up) reductions in self-reported drinking frequency, drinking related impairment, and heavy drinking in the past week, as well as post-traumatic stress disorder (PTSD) and complex PTSD symptoms, and improvement in self-reported emotion regulation. The enhanced intervention was associated with significantly greater sustained reductions in complex PTSD symptoms and resulted in medium/large effect size reductions in days of alcohol use (versus small effects by CBT). Emotion regulation enhancement of CBT for college student problem drinkers with interpersonal trauma histories warrants further investigation.

RESUMEN

OBJECTIVE: This study investigated between- and within-person associations among mean levels and variability in affect, diabetes self-care behaviors, and continuously monitored glucose in Latinos with type 2 diabetes. METHODS: Fifty participants (M [SD] age = 57.8 [11.7] years, 74% women, mean [SD] glycosylated hemoglobin A1c = 8.3% [1.5%]) wore a "blinded" continuous glucose monitor for 7 days, and they responded to twice daily automated phone surveys regarding positive affect, negative affect, and self-care behaviors. RESULTS: Higher mean levels of NA were associated with higher mean glucose (r = .30), greater percent hyperglycemia (r = .34) and greater percentage of out-of-range glucose (r = .34). Higher NA variability was also related to higher mean glucose (r = .34), greater percent of hyperglycemia (r = .44) and greater percentage of out-of-range glucose (r = .43). Higher positive affect variability was related to lower percentage of hypoglycemia (r = -.33). Higher mean levels of self-care behaviors were related to lower glucose variability (r = -.35). Finally, higher self-care behavior variability was related to greater percentage of hyperglycemia (r = .31) and greater percentage of out-of-range glucose (r = -.28). In multilevel regression models, within-person increases from mean levels of self-care were associated with lower mean levels of glucose (b = -7.4, 95% confidence interval [CI] = -12.8 to -1.9), lower percentage of hyperglycemia (b = -0.04, 95% CI = -0.07 to -0.01), and higher percentage of hypoglycemia (b = 0.02, 95% CI = 0.01 to 0.03) in the subsequent 10-hour period. CONCLUSIONS: Near-to-real time sampling documented associations of glucose with affect and diabetes self-care that are not detectable with traditional measures.

RESUMEN

The objectives of this study were to assess within-person hypotheses regarding temporal cognition-pain associations: (1) do morning pain flares predict changes in two afternoon adaptive and maladaptive pain-related cognitions, and (2) do these changes in afternoon cognitions predict changes in end-of-day pain reports, which in turn, carry over to predict next morning pain in individuals with fibromyalgia. Two hundred twenty individuals with fibromyalgia completed electronic assessments of pain intensity, pain catastrophizing, and pain coping efficacy three times a day for three weeks. Multilevel structural equation modeling established that afternoon catastrophizing and coping efficacy were parallel mediators linking late morning with end-of-day pain reports (controlling for afternoon pain), in line with prediction. Catastrophizing was a stronger mediator than coping efficacy. Moreover, afternoon cognitions and end-of-day pain reports served as sequential mediators of the relation between same-day and next-day morning pain. These findings align with assertions of cognitive-behavioral theories of pain that pain flares predict changes in pain both adaptive and maladaptive cognitions, which in turn, predict further changes in pain.

RESUMEN

Although psychological research on sport injury has long focused on negative responses to injury, investigators have begun to explore positive consequences as well. This study examined adversarial growth longitudinally after anterior cruciate ligament surgery and rehabilitation. Participants (N = 108) completed questionnaires measuring (a) aspects of adversarial growth before anterior cruciate ligament surgery and at 6, 12, and 24 months after surgery and (b) daily pain and negative mood for 42 days postoperatively. Although most participants reported little or no adversarial growth due to their injury and rehabilitation, significant increases over preoperative values were found at 6 months postsurgery for three aspects of adversarial growth. Daily pain and negative mood were positively associated with aspects of adversarial growth at each postoperative assessment. It appears that modest but detectable increases in aspects of perceived adversarial growth can occur after anterior cruciate ligament reconstruction and be related to indices of adversity experienced during rehabilitation.

RESUMEN

Previous studies indicate that topiramate reduces alcohol use among problem drinkers, with one study showing that the effect was moderated by a polymorphism (rs2832407) in GRIK1, the gene encoding the GluK1 kainate subunit. We examined whether the interactive effect of medication and genotype (1) altered the association between daily self-efficacy and later-day drinking; and (2) had an indirect effect on drinking via self-efficacy. In a 12-week, placebo-controlled trial of topiramate, we used daily interactive voice response technology to measure self-efficacy (i.e. confidence in avoiding heavy drinking later in the day) and drinking behavior in 122 European-American heavy drinkers. Topiramate's effects on both self-efficacy and drinking level were moderated by rs2832407. C-allele homozygotes treated with topiramate showed higher levels of self-efficacy and lower levels of nighttime drinking across the 12-week trial. Further, the interactive effect of topiramate and genotype on mean nighttime drinking levels was mediated by mean levels of self-efficacy. By modeling topiramate's effects on nighttime drinking across multiple levels of analysis, we found that self-efficacy, a key psychologic construct, mediated the effect of topiramate, which was moderated by rs2832407 genotype. Thus, it may be possible to use an individualized assessment (i.e. genotype) to select treatment to optimize the reduction in heavy drinking and thereby provide a personalized treatment approach.

RESUMEN

For individuals with chronic pain, the within-person influence of affect and goal cognition on daily work-related goal striving is not yet well understood. The present study tested the hypothesis that anticipatory goal cognition in the form of a morning work goal schema mediates the relations between morning affect and later (afternoon and evening) work goal striving. Working adults with chronic pain (N = 131) completed a 21-day diary with morning, afternoon, and evening assessments analyzed via multi-level structural equation modeling. At the within-person level, morning positive and negative affect were positively associated with morning work goal schemas; and morning work goal schemas, in turn, positively predicted both afternoon and evening work goal striving. Our findings underscore the complex dynamics over time of the relationship between affect and self-regulatory processes and have implications for future studies and for interventions to assist working adults with chronic pain.
