get_predilection_score: Compute a predilection score.

Description

This function computes a predilection score (predilection_score) for responses to items 1, 3 and 5 of the CSAPPA (Children's Self-Perceptions of Adequacy in and Predilection for Physical Activity; Hay, 1992) Questionnaire as they appear in the CAPL-2 Questionnaire. This score is used to compute the motivation and confidence domain score (mc_score).

Usage

get_predilection_score(csappa1 = NA, csappa3 = NA, csappa5 = NA)

Arguments

csappa1

A numeric (integer) vector representing a response to CSAPPA item 1 (valid values are integers between 1 and 4).

csappa3

A numeric (integer) vector representing a response to CSAPPA item 3 (valid values are integers between 1 and 4).

csappa5

A numeric (integer) vector representing a response to CSAPPA item 5 (valid values are integers between 1 and 4).

Value

Returns a numeric vector with values between 1.8 and 7.5 (if valid) or NA (if not valid).

Details

Valid values (integers between 1 and 4) represent the following responses:

• 1 = REALLY TRUE for me for "some kids" statements

• 2 = SORT OF TRUE for me for "some kids" statements

• 3 = REALLY TRUE for me for "other kids" statements

• 4 = SORT OF TRUE for me for "other kids" statements
