get_predilection_score {capl} R Documentation

## 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).

### 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

Other `capl` functions called by this function include: `validate_scale()`.

### Value

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

### Examples

```get_predilection_score(
csappa1 = c(1:3, 0),
csappa3 = c(4, 2, 1, "3"),
csappa5 = c(4, 4, 2, 2)
)

#  4.2 4.2 4.3  NA

```
