Assessment of adaptive behavior in people with intellectual disabilities: Design and development of a new test battery.

Background: Adaptive behavior is an important characteristic of people with intellectual disabilities, and it has been associated with a person's performance in social and work contexts. Indeed, adaptive behavior denotes what a person does independently, without help, support, reminders, or prompts. In Peru, available measures of adaptive behavior are commercial; thus, there is a need for an open-access tool to assess the adaptive behavior of people with intellectual disabilities.

Psychometric review of the perceived stress scale under CFA and Rasch models in Lima, Peru.

Stress is a public health disease that is increasing rapidly in the population worldwide, so it is necessary to take measures for detection and evaluation, through short scales. The purpose of the study was to analyze the psychometric properties of the Perceived Stress Scale (PSS) in a sample made up of 752 people with an age range of 18 to 62 years (M = 30.18, DE = 10.

Psychometric Properties of the Zarit Burden Interview in Informal Caregivers of Persons With Intellectual Disabilities.

Intellectual disability leads to a loss of autonomy and a high level of dependence, requiring support from another person permanently. Therefore, it is necessary to incorporate the assessment of caregiver burden in healthcare actions, to avoid putting the health of caregivers and patients at risk. In this sense, the study aimed to analyze the internal structure of the Zarit Burden Interview (ZBI) in a sample of caregivers of people with intellectual disabilities, to provide convergent and discriminant evidence with a measure of the risk of maltreatment, and to estimate the reliability of the scores from the Classical Test Theory and the Rasch Measurement Theory.

A New Story on the Multidimensionality of the MSPSS: Validity of the Internal Structure through Bifactor ESEM.

The internal structure of the Multidimensional Scale of Perceived Social Support (MSPSS) in adolescents has been evaluated with some factorial analysis methodologies but not with bifactor exploratory structural equation modeling (ESEM), and possibly the inconsistency in the internal structure was dependent on these approaches. The objective of the study was to update evidence regarding its internal structure of MSPSS, by means of a detailed examination of its multidimensionality The participants were 460 adolescents from an educational institution in the Callao region, Lima, Peru. The structure was modeled using unidimensional, three-factor and bifactor models with confirmatory factor analysis (CFA) and ESEM approaches.

Explanatory Model of Perceived Stress in the General Population: A Cross-Sectional Study in Peru During the COVID-19 Context.

Background: The COVID-19 pandemic had negatively impact mental health worldwide. High prevalence of stress had been previously reported in populations during this context. Many theoretical frameworks had been proposed for explaining the stress process, we aim to proposed and explanatory model for the genesis of perceived stress in Peruvian general population.
