The Nighttime Fears Scale: Development and psychometric evidence of a standardized self-report scale to assess nighttime fears in children

Validation of the Parent Version of the Nighttime Fears Scale (NFS-P) for Children Aged 3-8 Years

BACKGROUND

Nighttime fears are highly prevalent in children, ranging from normative fears to triggering fear-related anxiety disorders. The lack of available assessment instruments recently prompted the development of the Nighttime Fears Scale (NFS) for children aged 8-12 years. The present study aimed to adapt and psychometrically evaluate the parent-reported version for children aged 3-8 years (NFS-P) as a complement for younger children.

METHODS

Two hundred eighty-four Spanish-speaking parents (47% girls) completed the NFS-P and anxiety measures.

RESULTS

Confirmatory factor analyses supported a four-factor structure of the NFS-P. Strong internal consistency and validity evidence were obtained. No significant differences were found in NFS-P scores between sexes and age groups.

CONCLUSIONS

The findings offer support for the use of the NFS-P as a valuable instrument in clinical and research settings, supplementing the NFS for older children. Both scales provide an efficient means to comprehensively assess the presence and intensity of typical nighttime fears across preschool and school years.

A 25-Year Review of Nighttime Fears in Children: Past, Present, and Future

Nighttime fears in children are common, interfere with daily functioning, and result in considerable disruption in the family. The aim of the present review was to examine empirical literature from the past 25 years that investigated the assessment of nighttime fears in young children and the efficacy and effectiveness of psychosocial treatments for children's nighttime fears. The last review of this literature was in 1997 and examined studies conducted in and prior to 1995 (King et al. in Clin Psychol Rev 17:431-443, 1997). Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we conducted a systematic review of the literature aimed at providing a synthesis of the Randomized Control Trials (RCTs) and controlled single-case multiple baseline design studies (MBLs) on the treatment of nighttime fears in children. A search of the literature identified 12 articles, with nine studies utilizing a between-group randomized controlled trial design and three studies utilizing a multiple baseline design. Results demonstrated significant improvements in children's nighttime fears and reductions in disruptive nighttime behaviors using behavioral interventions and cognitive-behavioral strategies. This review provides a commentary on the effectiveness and limitations of the assessment and treatment approaches for nighttime fears in children and suggests directions for future research.
