Note. REL = first-degree relative sample, NC = non-psychiatric control sample, d = Cohen’s d effect size, TEPS = Temporal Experience of Pleasure Scale, PANAS = Positive and Negative Affect Scale, PRT = Picture Rating Task, PA = positive affect, SRLT = Self-Reported Liking Task.

^bAs noted in text, PANAS current affect group differences are also reported in Docherty et al., 2014, Schizophrenia Research. These do not constitute analyses from a separate sample.
