College student mental health: Psychiatric risk and psychological wellbeing.

Objective: To examine both psychiatric risk and psychological wellbeing in a college student sample drawn from a majority-minority university.

Participants: 100 participants (42% White; 70 females), mean age, 21.22 years.

Psychiatric risk and resilience: Plasticity genes and positive mental health.

Objective: The at-risk mental state (ARMS) for psychosis has long played a key role in diathesis-stress models of schizophrenia. More recent studies, however, have called for extending the boundaries of the ARMS construct beyond attenuated psychosis in nonhelp-seeking samples to include not only other vulnerability indicators but also protective factors related to genotype, mental health, personality, and cognition.

Method: Accordingly, we assessed in a sample of 100 college students, the ARMS construct with the Brief Prodromal Questionnaire (PQ-B) for psychosis, in conjunction with measures of positive mental health, childhood adversity, psychiatric symptoms, personality traits, social cognition, and genetic variables derived from assays of the serotonin transporter (5-HTTLPR) and the brain-derived neurotrophic factor (BDNF).

In search of positive mental health: Personality profiles and genetic polymorphisms.

Individuals vary greatly in their mental health and these differences may play a critical role in stress resistance, risk reduction and illness recovery. Here we ask how these differences may be related to normal variation in personality and genotype. One hundred healthy college students completed measures of mental health (Mental Health Continuum-Short Form [MHC-SF]), personality (NEO Five Factor Inventory) and adverse childhood experiences.

Risk and protective effects of serotonin and BDNF genes on stress-related adult psychiatric symptoms.

We focused on individual risk by examining childhood adversity and current psychiatric symptoms in a sample of 100 college students genotyped for both the serotonin transporter (5-HTTLPR) and the brain-derived neurotrophic factor (BDNF). Naturally occurring allelic variation in 5-HTTLPR (short/long) and BDNF (valine/methionine) have been strongly implicated in stress-related psychiatric risk, but the combined effects of these alleles on psychological functioning have yet to be fully elucidated. Univariate analysis revealed gene-environment correlations linking heightened psychiatric risk with past childhood adversity for short but not long 5-HTTLPR allelic carriers and for valine (Val) but not methionine (Met) BDNF allelic carriers.
