Page 59 - Zero for nine: Reducing alcohol use during pregnancy via health counselling and Internet-based computer-tailored feedback

Partner support to prevent prenatal alcohol us
were assessed with 10 items measured on a 5-point Likert scale (1 = fully
disagree, 5 = fully agree). Five questions measured pros or advantages
(e.g. If I support my pregnant partner to abstain from alcohol during
pregnancy, my partner will appreciate that; α = 0.84) and five questions
measured cons or disadvantages (e.g. If I support my partner to abstain
from alcohol during pregnancy, my partner will get irritated; α = 0.86)
of providing support. Social influences with regard to providing support
were assessed with six items on a 5-point scale (1 = fully disagree;
5 = fully agree) concerning norms (My friends/family consider(s) it
important that I support my pregnant partner not to drink alcohol; α = 3 0.95), modelling (My friends/family support(s) their partner to abstain
from alcohol during pregnancy; α = 0.93) and encouragement (My friends/family encourage(s) me to support my partner to abstain from alcohol during pregnancy; α = 0.94). Self-efficacy was measured by eight items asking respondents to indicate on a 5-point scale (1 = very difficult; 5 = not difficult at all) their difficulty with supporting their partner to abstain from alcohol in certain situations (e.g. When my partner and I have something to celebrate; α = 0.94).
Intention was assessed with one item asking respondents to indicate on a 5-point scale (1 = no, definitely not; 5 = yes, definitely) if they had the intention to support their partner not to drink alcohol during the remainder of the pregnancy.
The outcome variable was partner support to abstain from alcohol during pregnancy. This variable was assessed by one item: I support my spouse not to drink alcoholic beverages during her pregnancy (1 = no, definitely not; 5 = yes, definitely).
