Within-person affect dynamics among individuals in residential treatment for opioid use disorder: An ecological momentary assessment study.

Ecological momentary assessment is increasingly leveraged to better understand affective processes underlying substance use disorder treatment and recovery. Research in this area has yielded novel insights into the roles of mean levels of positive affect (PA) and negative affect (NA) in precipitating drug craving and substance use in daily life. Little of the extant substance use disorder treatment research, however, considers dynamic patterns of PA and NA, separately or in relation to one another, or how such patterns may differ from those observed among nonclinical samples.

The day-level effects of recovery community center attendance on indicators of recovery wellbeing and risk.

Background: Recovery community centers (RCCs) are a relatively new resource in the recovery support landscape aimed at building their members' recovery capital. In recent years, interest in the value of RCCs has grown, however, no studies have used within-person methods to consider how RCCs may impact the day-to-day lives of their attendees. Using within-person data drawn from members of RCCs, this study examined how visiting RCCs was associated with several same-day indicators of recovery wellbeing and risk: daily sense of meaningfulness, recovery identity, negative affect, and positive affect.

Validation and Psychometric Properties of the Original Grit Scale (Grit-O) Among Cambodian Adolescents.

Grit, a person-level trait defined as having "perseverance and passion for long-term goals", may be particularly important in helping Cambodian youth to succeed despite the extreme challenges they face. To date, the Original Grit Scale (Grit-O) has not been translated in Khmer or validated for a sample of Cambodian youth.
