The aim of this study was to employ qualitative and quantitative survey methods in a concurrent mixed model design to assess stressors and strains in graduate assistants. The stressors most frequently reported qualitatively were work overload, interpersonal conflict, and organizational constraints; the most frequently reported psychological strains were frustration, anger, and anxiety. The groups formed by the qualitative incident reported (e.g., work overload) partially discriminated between those scoring high versus low on the corresponding stressor scale. Finally, participants who qualitatively reported a stressor indicated more physical symptoms on a quantitative scale. The results show support for the combination of qualitative and quantitative methods in stress research, as the two types of measures provided different information about stressors and strains.
