Minnesota Nicotine Abstinensskala
Tidsramme: Under deltagernes 1. og 2. besøg. Spørgeskemaet vil blive administreret 2 gange i hver rygesession: før og efter en ad lib-brugsperiode på ca. 45 minutter.
|
Denne skala bruges til at vurdere, i hvilket omfang produktbrug reducerer tobaksabstinenssymptomer, og består af 11 punkter med en score på 0 - 100.
Disse elementer præsenteres som visuel analog skala med emne (mål) centreret over en vandret linje forankret til venstre med slet ikke og til højre med ekstrem.
