[영문]Increased parent school involvement is associated with better academic outcomes; yet, proximal contributors to this effect remain understudied. We focus on one potential proximal contributor, youth's positive and negative future self-images or qqqquot;possible selves,qqqquot; reasoning that if parent school involvement fosters possible selves, then interventions aimed at enhancing youths' possible selves should moderate the negative effect of low parent school involvement. We examine a 2-year follow-up of a randomized clinical trial of a possible self-based intervention (N 239), demonstrating with regression equations that the intervention moderated the association of low parent school involvement with worse grades and less school-engaged behavior. Low parent school involvement negatively influenced achievement among control, not intervention youth, suggesting that school-based, possible self-focused interventions can moderate the undermining effect of low parent school involvement.
