Clinicians could benefit from paying special attention to the subfactors identified, as these findings may have implications for treatment choice for patients with chronic depression.
The factor structure in our sample was best explained by a general depression factor, one specific factor pertaining to self-criticism, and one consisting of the somatic items fatigue, disturbance of sleep, and appetite. Clinicians could benefit from paying special attention to the subfactors identified, as these findings may have implications for treatment choice for patients with chronic depression.
Men who have sex with men (MSM) are at increased risk of mental health problems. Few studies have examined the risk factors for mental health problems of Chinese MSM and identified potential moderators using a longitudinal design.

The present study examined the effect of stress and avoidant coping on depression among MSM, and the moderating role of age on such relationship.

A 6-month observational prospective cohort study was conducted among Chinese MSM. Respectively 592 and 402 MSM completed a survey at baseline and 6-month follow-up.

The prevalence of probable depression was 36.1% at baseline and 34.1% at 6-month follow-up. After adjusting for background characteristics and baseline depression score, both stress (β=.22, p<.05) and avoidant coping (β=.14, p<.05) showed significant positive relationship with depression at 6-month follow-up. The interaction effect of age and stress / avoidant coping was also significant. The effect of stress on depression was stronger among younger MSM, and the effect of avoidant coping on depression was significant among younger MSM but non-significant among older MSM.

Mental health promotion for MSM should reduce stress and avoidant coping, and specific intervention should be designed for younger MSM.

Eating disorders (ED) and obsessive-compulsive disorder (OCD) are highly comorbid, but little is known about how this comorbidity is maintained. Prior research suggests that obsessive thoughts and perfectionism may be shared maintenance factors for EDs and OCD.

The current study used network analysis to (1) identify bridge pathways in an ED-OCD comorbidity network and (2) test if perfectionism symptoms bridge between ED-OCD symptoms in a combined network model including ED, OCD, and Perfectionism symptoms. Participants (N=1,619) were a mixed sample of undergraduate students and individuals diagnosed with EDs.

Difficulty controlling thoughts was the symptom with the highest bridge centrality in both models, connecting with ED-related worry and doubts. In the ED-OCD-Perfectionism comorbidity network, doubts about simple everyday things and repeating things over and over bridged between ED and OCD symptoms. Additionally, specific and distinct pathways were identified between OCD and two types of ED pathology restricting (checking compulsions and rigidity around food) and binge eating (hoarding and binge eating symptoms).

Due to the cross-sectional nature of the data, no directional inferences can be made. Due to a higher OCD symptom prevalence rate than reported in previous studies, our undergraduate sample may not be representative of other college populations.

The presence of intrusive cognitions and maladaptive perfectionism may contribute to the maintenance of co-occurring ED and OCD symptoms. These findings begin to delineate specific pathways among OCD and ED symptoms, which can be used in the development of interventions to disrupt connections among these disorders.

Impulsivity and perfectionism are transdiagnostic personality factors that have been studied extensively and shown to relate to externalizing and internalizing pathology respectively. Typically, these personality factors are antithesized, with impulsivity characterized by lack of control and perfectionism characterized by rigid overcontrol.

The current study (N=1,353 undergraduate students) used latent profile analysis to identify subgroups based on impulsivity and perfectionism dimensions and tested the relations of these subgroups with the symptomatology of ten prevalent types of psychopathology (depression, worry, social anxiety, attention-deficit hyperactivity disorder inattentive subtype, attention-deficit hyperactivity disorder impulsive-hyperactive subtype, alcohol use, obsessive-compulsive disorder, posttraumatic stress disorder, restrictive eating pathology, and binge eating pathology).

The latent profile analysis identified four meaningful subgroups high perfectionism, high impulsivity, combincan co-occur. Further, the co-occurrence of these personality traits may heighten risk for psychopathology and help explain comorbidity across internalizing and externalizing disorders. Future research should continue to investigate the presentation, prevalence, and treatment for individuals high in both perfectionism and impulsivity.
The proportion of older adults is increasing due to demographic changes. Depression belongs to the most common mental disorders in late life. The loss of an emotionally significant person is a risk factor for the development of depression. click here The aim of this study is to analyze the association between depression and grief burden resulting from loss. Based on prior evidence, we examined loneliness as a possible mediator and social support as possible moderator of this association.

The cross-sectional analyses are based on a sample (N=863) of study participants aged 75+ (M=81.4 years, SD=4.4, 62.2% female) with loss experience deriving from the multicenter prospective German cohort study AgeMooDe. Regression analyses (moderated mediation) were performed.

With increasing age (β=0.10, p=.005) and grief burden (β=0.33, p <. 001) depression severity increased. There was an indirect mediating effect of loneliness on the correlation of grief burden and depression (b=0.04, CI [0.03, 0.05]), but no moderating effect of social support on the correlation of grief burden and loneliness.
