Rator one of the settings was randomly selected. This procedure yielded 126 publications with data from 146 independent Peficitinib price samples encompassing a total of 15,034 families. The studies that were included in the meta-analyses are presented in Table 1.Conceptual Analysis: the Sorting TaskBecause the grouping of dependent variables may have an important effect on the outcome of a meta-analysis, a sorting task with experts was used (see [19], [188]). Experts were defined as persons who had been trained and actively involved in research on parenting for several years and who were at least participating in a relevant graduate program. A total of 10 experts were asked. Five of the coders had a doctoral degree; the others were advanced graduate students. Overall, 313 parental control constructs were identified from the selected publications. Because some of the 313 constructs were almost identical, the first, second, and third Bay 41-4109 cost authors together grouped the constructs that were obviously (near-)identical. Any differences were resolved through discussion and consensus. The grouping resulted in a set of 147 different constructs. Each construct was printed on a separate card, including the definition that was given in the paper and examples of the specific parenting construct. Any information about the source of the construct was left out. Separate sets of cards were made for the four settings in which parental control was observed (e.g., free play, problem solving, discipline setting, naturalistic). This was done because certain aspects of parental control may be evaluated differently depending on the setting in which it was observed [29]. Experts were asked to sort the constructs into three groups of parental control (appropriate/positive, not-appropriate/negative, and neutral, with regard to optimal child development), separately for the four different observation settings. The appropriate/positive and not-appropriate/negative categories correspond with the autonomy-supportive and controlling strategies as proposed by self-determination theory [12]. A neutral category was included only for the sorting task, because we wanted to examine only the most pure forms of controlling and autonomy-supportive strategies in the actual meta-analysis. Agreement between the experts was satisfactory (kappas .66?82, average .75). For 117 of the constructs, at least 8 out of 10 experts agreed on sorting the construct in the appropriate/ positive, not-appropriate/negative, or neutral control category. The 30 remaining constructs with 70 agreement or less were discussed by the first and last authors. For 12 of these 30 constructs the two authors reviewing the experts’ sorts agreed on one of the existing categories. The remaining 18 constructs were ambiguous or contained both positive and negative elements in one composite score, and therefore could not be grouped under autonomy-supportive or controlling strategies. The outcomes of the expert sort can be found in S2 Table. Further, the constructs that were identified by the experts as controlling (n = 60) were divided in psychological control and harsh physical discipline by the first and second authors. This search was guided by the content of questionnaires and observation scales that are widely used to assess psychological control (i.e., Child Report of Parental Behavior Inventory; [189], Parental Psychological Control measure; [28], Psychological Control Scale; [10]).
