AI Article Synopsis
- Existing measures of adolescent optimism are not well-suited for the African context, leading to the development of a new scale tailored for this setting.
- The researchers created the Mabrouk's Measure of Adolescent Optimism (MMAO) through a five-step process, including literature reviews and testing with a sample of 1616 adolescents in Kenya.
- The MMAO showed strong internal consistency and reliability, with supportive factor analysis indicating it's valid for assessing optimism across various demographics in Kenya and potentially similar regions.
Article Abstract
Several measures of adolescent optimism exist. However, none of these measures have been developed in the African setting, and only a few of the available measures have been validated for use in this setting. We aimed to develop and validate a culturally appropriate measure for this context. We employed an exploratory sequential mixed methods design using a five-step approach to tool development, comprising literature reviews, construct clarification, item development, piloting, and scale evaluation. We constructed a six-item scale, the Mabrouk's Measure of Adolescent Optimism (MMAO). In a sample of 1616 adolescents from Kenya, the MMAO demonstrated adequate internal consistency (both Cronbach's alpha and McDonald's Omega > 0.80) and test-retest reliability (ICC = 0.46). Factor analysis supported a unidimensional scale with adequate criterion and divergent validity as well as measurement invariance across sex, age (younger vs. older adolescents), residence (rural vs. urban), schooling status (in-school vs. out-of-school adolescents), and language of administration (Swahili vs. English). We report on the development and validation of a new scale of adolescent optimism that can be used to assess optimism among adolescents in Kenya and similar contexts. Preliminary evidence shows support for this new measure's reliability and validity, although additional tests are needed.

Experimental psychologists and psycholinguists increasingly turn to online research for data collection due to the ease of sampling many diverse participants in parallel. Online research has shown promising validity and consistency, but is it suitable for all paradigms? Specifically, is it reliable enough for individual differences research? The current paper reports performance on 15 tasks from a psycholinguistic individual differences battery, including timed and untimed assessments of linguistic abilities, as well as domain-general skills. From a demographically homogenous sample of young Dutch people, 149 participants participated in the lab study, and 515 participated online.

Developing social-emotional skills is crucial for all children and adolescents, particularly those experiencing social and emotional difficulties. This study used network analysis to identify the central skills and network association of different social-emotional skills and investigated how these networks differ between childhood and adolescence. Data were obtained from the 2019 Survey on Social and Emotional Skills by the Organization for Economic Co-operation and Development.

Background: Conflict-induced displacement is a greater risk factor for mental health challenges, especially in countries where people have limited access to mental health services. This study examined the prevalence of mental distress, post-traumatic stress disorder (PTSD), and their relationship with key demographic variables and psychological capital among conflict-induced Internally Displaced People (IDP) in the Wag-Hemra Zone, Amhara Region, Ethiopia.
Methods: The study used a cross-sectional quantitative design, and simple random sampling was used to recruit 367 IDPs from the Weleh IDP camp in Sekota town.
