A new questionnaire to assess positive emotions in children
The purpose of this study was to design and validate a new instrument to measure the positive emotional experience of children 8 to 12 years of age. The pilot sample consisted of 445 children (n = 221) and girls (n = 224), with a mean age of 9.54 years (SD = 1.25), belonging to different provinces of Argentina. The final sample consisted of 1046 children (n = 540) and girls (n= 505) with an average age of 9.74 years (SD = 1.33). After being analyzed according to different parameters of validity and reliability, the final questionnaire was composed of 24 items and four dimensions: (a) joy and gratitude (α = .93), (b) serenity (α = .74), (c ) sympathy (α = .66), and (d) personal satisfaction (α = .72). The Cronbach alpha for the total scale was .95. Psychometric Study results were appropriate, with a good discriminative power of items, high internal consistency and consistent factor structure.
