Three reasons BP have been identified: Deliberate procrastination, mindless and strategic delay. Developing instrument to assess the allows better identification of patterns behaviors tailored interventions. The present study aims develop psychometric properties (RBPS). Bedtime procrastination Reasons Procrastination Scale Method: sample included adults living in Portugal (N = 653). Validity reliability analyses were conducted. Results: Principal component analysis suggested that RBPS composed two factors (factor 1 - deliberate reasons; factor 2 reasons). Confirmatory supported two-factor structure scale (e.g., CFI .984; TLI .976 RMSEA .053). demonstrated good internal consistency, a Cronbach's alpha coefficient .85 1, .72 2. Convergent validity was by significant correlations number activities people engage before going bed, BP, bedtime gap, fall-asleep time wake-up gap.

ABSTRACT Background Sickle cell disease (SCD) confers neurological risks that contribute to cognitive and academic difficulties. Clinical guidelines state cognition should be monitored using signaling questions. However, evidence is lacking regarding the extent which questions accurately identify children with issues. Procedure Caregivers of youth SCD between ages 7 16 years ( n = 89) responded a question about their child's performance: “How would you rate your performance relative peers?” Response choices included below grade level, on or above level. Youth completed Wechsler Intelligence Scale Intelligence, Fifth Edition assess functioning. Results Most were described by caregivers as being level (67%), followed (21%), (11%). Cognitive testing revealed 36% participants had low IQ (≤85; i.e., ≥1 SD mean), 60% an within normal limits (86–114; <1 4% high (≥115; mean). Academic grouping was significantly associated differences across domains (all p < 0.001). functioning varied for younger (ages 7–11; all ≤ 0.002) but not older 12–16; ≥ 0.05). The question's sensitivity identifying those difficulties (42%–54%); specificity, negative predictive value, positive value estimates acceptable (87%–93%, 74%–84%, 53%–79%, respectively).
