Publication Metadata only Discrepancies between beliefs and practices on sleep as a factor of insomnia and negative feelings(Sage Publications Inc, 2022) Ray-Yol, Elçin; N/A; Department of Psychology; N/A; Department of Psychology; Söğüt, Meryem; Yedidağ, Ecem; Özdemir, Ahmet Berk; Atalay, Ayşe Altan; Master Student; Undergraduate Student; Master Student; Teaching Faculty; Department of Psychology; Graduate School of Social Sciences and Humanities; College of Social Sciences and Humanities; Graduate School of Social Sciences and Humanities; College of Social Sciences and Humanities; N/A; N/A; N/A; 205807Two online surveys were conducted in Japan to develop and validate the Sleep Belief-Practice Index (SBPI) scales, a pair of new scales designed to measure beliefs (SBPI-B) and practices (SBPI-P) on sleep and its environment. Their discrepancies (SBPI-D) were calculated as differences between SBPI-B and -P. In Survey 1 (N = 400), survey data of the pilot version of the scales were entered into an exploratory factor analysis to obtain a meaningful set of scale items. In Survey 2 (N = 2952), survey data were entered into a confirmatory factor analysis and then correlation analyses to confirm associations of SBPI-D with insomnia and positive and negative feelings. Furthermore, participants were categorized into four groups according to the degree and combination of sleep beliefs and practices to compare the status of insomnia and positive and negative feelings by the groups. As a result of factor analyses, we obtained 13 common item scales of SBPI-B and -P. SBPI-D was positively correlated with insomnia and negative feelings. In addition, the group with high-scoring beliefs in SBPI-B and low-scoring practices in SBPI-P showed the most severe insomnia and negative feelings among the four groups. These results suggest that the belief-practice discrepancy about sleep can explain one aspect of insomnia.Publication Metadata only Problem orientation and psychological distress among adolescents: do cognitive emotion regulation strategies mediate their relationship?(Sage, 2022) Ray-Yol, Elçin; N/A; Department of Psychology; N/A; Department of Psychology; Söğüt, Meryem; Yedidağ, Ecem; Özdemir, Ahmet Berk; Atalay, Ayşe Altan; Master Student; Undergraduate Student; Master Student; Teaching Faculty; Department of Psychology; Graduate School of Social Sciences and Humanities; College of Social Sciences and Humanities; Graduate School of Social Sciences and Humanities; College of Social Sciences and Humanities; N/A; N/A; N/A; 205807Adolescence is a critical period for the development of attitudes and skills crucial in determining vulnerability for psychological distress. The current study aimed to focus on the association of problem orientation and cognitive emotion regulation strategies with psychological distress and demonstrate the mediator roles of adaptive and maladaptive cognitive emotion regulation strategies in the association of problem orientation with psychological distress. Data were collected from 335 adolescents (167 female) aged 14-to-18 years (M= 14.7, SD= .95) via measures of problem orientation, cognitive emotion regulation, and psychological distress. The results revealed that maladaptive emotion regulation strategies (self-blame and other-blame) mediated the association of negative problem orientation with psychological distress. The findings emphasize the crucial roles of blaming-focused strategies in this relationship.
