5 The direction of effects is family-specific 157 RESULTS Descriptive Statistics and Correlations Both perceived parenting and adolescent affect fluctuated from one day to the next (for two examples, see Fig. 2). The intraclass correlations (ICCs) for the parenting variables indicated that 56% to 67% of the variance was due to stable between-family differences and 33% to 44% due to daily fluctuations within families. For adolescent positive and negative affect, 62% and 47% of the variance was due to stable between-family differences, respectively, and the remaining 38% to 53% was due to daily fluctuations within families (Table 1). Figure 2 Daily Fluctuations in Parental Psychological Control and Adolescent Positive Affect Reported by Two Participating Adolescents Positive affect Psychological control Note. Timeseries of two participants, including their daily mean scores on their level of positive affect and perceived parental psychological control across 100 days. Response scale ranged from 0 to 100. Most parenting dimensions correlated weakly with adolescent affect at the withinfamily level (rs between -.23 and .20; see Table 1), with the exception of the moderate correlation between parental warmth and adolescent positive affect (r = .33, p < .001). These within-family correlations indicate that, on average, adolescents reported more parental psychological control on days when they experienced less positive affect (r = -.13, p < .001) and more negative affect (r = .17, p < .001).
