Pressurizing or encouraging: Health behaviors among long-distance couples

Couples in long-distance relationships face unique challenges that affect their health outcomes and relationship dynamics in ways that are different from couples in close proximal relationships (PR). The results of previous literature analyzing health outcomes for long-distance relationship (LDR) couples have been mixed, and factors such as couple satisfaction and gender of the individuals contribute to the variance. This study examined the good health practices of couples in LDRs, the ways in which partners influence each other's health, and the health outcomes of these couples as compared to couples in PRs. Multilevel multivariate analysis showed that couples in LDRs had better health practices than those in PRs, and men overall had poorer health practices than women. There was no main effect seen for LDRs when we examined strategies used for influencing health. There was a main effect for gender, though, and we found that women tend to use more collaborative and pressurizing strategies for influencing their partner's health. On health indices, we found that LDR couples tended to have lower levels of fatigue and sleep disturbance as compared to PR couples. In the adjusted model with covariates, which included age, income, couple satisfaction, and married or unmarried couples, we found that lower couple satisfaction and lower income significantly predicted poorer health on all health indices. These results are discussed in light of unequal gender roles, social control, and positive aspects of LDRs on health in an attempt to understand LDRs better and destigmatize the narrative of these relationships as 'less than' PRs. Implications for health and mental health practitioners are also discussed.

Ending the silo effect: A test of the relational domain spillover model

Couple interventions are limited in their effectiveness for reducing marital distress and dissolution. One explanation for this may be the narrow focus on conflict management and a limited understanding of how other domains in marriage influence one another over time. We present the first test of the relational domain spillover model (RDSM) to understand the extent to which poor functioning in either positive or negative areas of the relationship spill over into other aspects of relationship functioning across time. Husbands and wives reported annually on the quality of five relationship domains (emotional intimacy, sex, support, power/control, and conflict) over the first seven years of marriage. Longitudinal dyadic multilevel modeling techniques were used to examine how domains change over time and how earlier declines in positive areas of couple functioning predict later problems in negative areas of couple functioning and vice versa. We found support for both directions of the RDSM model. Earlier declines in sexuality and support predicted later declines in conflict, and, for wives, earlier declines in couple sexuality were linked to later control issues. Earlier declines in conflict communication and control predicted later problems with emotional intimacy. For men, longitudinal associations between sexuality and conflict, and control, were bidirectional. These findings point to the need to move toward a multi-dimensional, dynamic conceptualization of relationship functioning across time and the importance of focusing on different relational domains as targets for couple interventions.

Treating depressive symptoms among veterans in primary care: A multi-site RCT of brief behavioral activation

BACKGROUND

Behavioral activation is ideal for embedded behavioral health providers (BHPs) working in primary care settings treating patients reporting a range of depressive symptoms. The current study tested whether a brief version of Behavioral Activation (two 30-minute appointments, 2 boosters) designed for primary care (BA-PC) was more effective than primary care behavioral health treatment-as-usual (TAU) in reducing depressive symptoms and improving quality of life and functioning.

METHODS

Parallel-arm, multi-site randomized controlled trial. 140 Veterans were randomized to BA-PC or TAU and completed assessments at baseline, 6 weeks, 12 weeks, and 24 weeks.

RESULTS

Reductions in depressive symptoms were observed in both groups between baseline and 3-weeks prior to any treatment, with continued reductions among those in the BA-PC condition through 12-weeks. However, there was no significant condition X time interaction at 12-weeks. Quality of life and mental health functioning were significantly improved for those in the BA-PC condition, compared to TAU, at 12 weeks.

LIMITATIONS

Generalizability to a broader population may be limited as this sample consisted of veterans. Although engagement in TAU matched other prior work, it was lower than engagement in BA-PC, which also may compromise results.

CONCLUSIONS

Although this study found that both TAU and BA-PC participants showed a decline in depressive symptoms, improvements in functioning and quality of life within those assigned to BA-PC, strong treatment retention and feasibility of BA-PC, and significant reductions in depressive symptoms among those with more severe baseline depressive symptoms are encouraging and support continued research on BA-PC. This trial was registered in clinicaltrials.gov as Improving Mood in Veterans in Primary Care (NCT02276807).

Personalized medicine in traumatic brain injury

Patients who have sustained a mild traumatic brain injury (TBI) from both civilian and military populations exhibit clinical symptoms of varying severity with minimal to profound impact on their daily functioning. Although most patients make a full recovery, a subgroup of mild TBI patients develop cognitive, somatic, and neurobehavioral sequelae that generally resolve over 3 to 6 months; a smaller subgroup develop persisting symptoms. The reason why a mild TBI results in varying clinical symptoms is currently unknown. Based on evidence that microRNA species in peripheral blood mononuclear cells (PBMCs) may reflect molecular alterations in neurodegenerative disorders, it can be hypothesized that at early, preclinical phases of the disease, PBMC may provide an ideal and clinically assessable "window" into the brain. Thus, it is conceivable that changes in the expression profile of clinically accessible biological indices (biomarkers), such as microRNA in PBMC, may reflect molecular alterations following TBI that contribute to the onset and progression of TBI phenotypes including chronic traumatic encephalopathy. It is possible that the availability of TBI biomarkers may provide potential elements with clinical relevance to prevention, prognosis, and treatment of postconcussive disorders.
