The Social Support Networks Scale (SSNS) for Family Caregivers of Children with Cancer: A Psychometric Evaluation.

Currently, information about the psychometric properties of the Social Support Networks Scale (SSNS) for family caregivers of children with cancer is not yet available; therefore, there is no empirical evidence of its validity and reliability to support its use in this population. The aim of this study is to determine a factorial model of the SSNS, estimate its internal consistency reliability, describe its distribution, and check its concurrent validity. A convenience sample of 633 family caregivers of children with cancer hospitalized in a National Institute of Health in Mexico City was collected.

Evaluating different versions of the Body Shape Questionnaire and invariance across age in Mexican women.

Methods: Women attending middle school (n = 261), high school (n = 245) and university (n = 296) participated in the study; their average age was 16.52 years (SD = 2.
