Ecological evidence that affect and perceptions of drink effects depend on alcohol expectancies.

ABSTRACT:

Aims

(1) To compare affective changes over drinking and non-drinking days among frequent drinkers and (2) to evaluate whether drinkers' expectations influence affective changes and perceived pleasure and relief from drinking.

Design

Observational study involving ecological momentary assessments collected via electronic diaries during the course of 3 weeks.

Setting

Drinkers' usual settings in Columbia, MO, USA.

Participants

A total of 400 adult, frequent drinkers, aged 18-70 years.

Measurements

Ecological assessments included morning reports, pre-drinking random prompts, user-initiated first-drink reports and device-prompted follow-ups over drinking episodes. Participants rated positive (enthusiastic, excited, happy) and negative (distressed, sad) affect
