OBJECTIVES: To examine student’s anxiety. 2. To identify relationship between anxiety and academic achievement. 3. To establish academic achievement prediction model by 1. Anxiety, 2. Social support and 3. Demographic data.

METHODS: A cross-sectional survey study was performed at college of Pharmacy, Burapha University, Thailand, in 2017. All population (1^st-5^th year students), n=627, were selected as the census sample however, only 568 students participated, the return rate was 90.59%. A 2 page questionnaire consisted of Thai Spielberger’s Form (TSF) and socioeconomic status. The TSF measured 2 dimensions namely: emotional and worry. It consisted of 14 measurement variables measured by visual analogue scale.

RESULTS: The TSF’s internal consistency was detected by Cronbach’s Alpha yield r=0.849. The second year student had the most anxiety score compared to all students (1^st to 5^th year). Anxiety had a negative correlation to GPAX (r = -0.084, p=0.047, Pearson’s correlation). Hierarchical Stepwise Multiple Regression Analysis was employed to establish academic achievement prediction model by using anxiety, social support and gender as the predictors: GPAX = 0.061 boy/girl-friend + 0.109 friend support *+0.092 anxiety* -0.017 family support -0.008 parents -0.128 gender**. (p-value 0.010, 0.030 and 0.002 respectively) with R-square 0.410

CONCLUSIONS: Gender had the biggest impact on academic achievement and 3 significant predictors of Academic Achievement model were gender, friend support and anxiety.
