Insights

The Parental Needs Scale for Rare Diseases (PNS-RD) is valid and reliable for Turkish parents of children with rare diseases. This tool helps identify unmet needs to guide support programs for these families.

Area of Science:

  • Pediatric Nursing
  • Rare Diseases
  • Psychometrics

Background:

  • Parents of children with rare diseases (RDs) experience significant economic, psychosocial, and physical burdens.
  • Long-term care issues associated with RDs negatively impact family quality of life.
  • Developing effective support systems requires understanding the specific needs of these parents.

Purpose of the Study:

  • To assess the validity and reliability of the Parental Needs Scale for Rare Diseases (PNS-RD) in the Turkish population.
  • To establish a psychometrically sound instrument for evaluating the needs of parents caring for children with RDs in Turkey.
  • To lay the groundwork for culturally adapted support interventions.

Main Methods:

  • The study included 264 parents of children diagnosed with rare diseases.
  • Data were collected using a socio-demographic form and the PNS-RD scale.
  • Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) were employed for validity assessment, alongside Cronbach's alpha and Pearson correlation for reliability.

Main Results:

  • The PNS-RD explained 76.10% of the variance, with factor loadings exceeding the 0.30 threshold.
  • Good statistical fit was indicated by a Root Mean Square Error of Approximation (RMSEA) below 0.080.
  • The scale demonstrated strong internal consistency and high reliability across its sub-dimensions for the Turkish population.

Conclusions:

  • The Turkish version of the PNS-RD is a valid and reliable instrument for assessing the needs of parents with children suffering from rare diseases.
  • This validated scale will aid pediatric nurses and researchers in identifying unmet family needs.
  • Findings will inform the development of targeted intervention and support programs for this vulnerable population.
