Contraceptive Behavior Scale (Wang et al., 2013)

Contraceptive methods chosen and used by adolescents and young adults females, 5 Items, Ages 15-19

Populations: Female Adolescents and Young Adults
Age ranges: 15-19
Languages: Chinese
Countries: Taiwan

Items

I practice contraception each time when I have sex
I have a preferred contraceptive method used to prevent pregnancy (e.g. safe period combined with condom, coitus interruptus, condom)
I pay attention to any contraceptive information to enable me to have good contraceptive practice
When I am doubtful about the safety of contraceptive method after having sex with my partners, I will take other compensatory methods (e.g. take emergency contraceptive pills or consult friends to take action)
I use contraceptive method accurately

Responses

Items used a 5 point Likert-type scale, 0 (totally no correspondence)–4 (total correspondence).

Scoring

“Participants respond according to the degree of consistency between their actual practice and the statement of the item, which is rated from 0 (totally no correspondence)–4 (total correspondence). Higher scores indicated better contraceptive behaviours.” (Wang et al., 2013)

Definitions

Face validity: How well a measure appears to represent the construct it is supposed to be measuring.

Convergent validity: How well a measure correlates with other hypothetically-related measures.

Construct validity: The extent to which a measure reflects the construct it was designed to evaluate.

Internal consistency: The extent to which items in a scale capture aspects of the same construct.

Test-retest: The degree to which measurement scores are consistent over a short period of time (usually 2 weeks).

Readability: The ease with which a reader can understand the questionnaire items.

Key

Green: Meets validation criteria
Red: Does not meet validation criteria
