This score is used to compute the motivation and confidence domain score (mc_score).

Usage

get_adequacy_score(csappa2 = NA, csappa4 = NA, csappa6 = NA)

Arguments

csappa2

A numeric (integer) vector representing a response to CSAPPA item 2 (valid values are integers between 1 and 4).

csappa4

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

csappa6

A numeric (integer) vector representing a response to CSAPPA item 6 (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
