110 Chapter 4 SUPPLEMENT S4.7 Adolescents’ feelings about the targets After watching each video, adolescents were asked to answer three questions: (1) “How connected do you feel with this person at this moment?”, (2) “How do you feel about this person at this moment?”, and (3) “How do you feel at this moment?”. Responses to the question “How do you feel about this person at this moment?” were highly correlated with adolescents’ feelings of connectedness (r=.72, p <.001) and showed similar effects, which are presented here in this supplement. We performed a generalized linear mixed regression model with gaze direction and target on adolescents’ affect ratings to the question “how do you feel about this person at this moment?”. HCs reported more positive feelings about the targets (B = -0.42, SE = 0.06, t(642) = -7.44, p <.001, d = 0.56) in response to direct versus averted gaze videos. In addition, adolescents’ feelings about the targets were dependent on the target in the videos (χ2(2) = 750.18, p <.001). Bonferroni corrected post hoc analyses revealed that they felt more positive about their parent versus an unfamiliar peer (p <.001, d = 2.17) or adult (p <.001, d = 2.20), but did not significantly differ in how they felt about an unfamiliar peer versus adult (p = 1.000). There was no significant interaction between gaze direction × target on adolescents’ feelings about the targets with the others (p = .689). Regarding differences in adolescents’ feelings about the targets between DEP and HC adolescents, we found a significant interaction between group × target (χ2(2) = 29.98, p <.001). DEP adolescents reported to feel less positive about their parent compared to HC adolescents (p = .002), while no differences were found in how positive they felt about an unfamiliar peer or adult in response to their videos (p = 1.000, for both). In addition, we found a significant interaction between group × gaze direction (χ2(1) = 4.62, p = .032), showing that DEP adolescents did not significantly differ in how positive they felt about the targets after direct versus averted gaze videos (p = .172), while HC adolescents did feel more positive about the targets after direct versus averted gaze videos (p <.001). Lastly, DEP adolescents reported to feel less positive about the targets in general compared to HC adolescents (χ2(1) = 4.18, p = .041). There was no significant three-way interaction between group × gaze direction × target on adolescents’ feelings about the targets (p = .437).
