We examined intensified job demands (IJDs) and selecting-optimizing-compensating (SOC) strategies as predictors of job performance (task performance, organizational citizenship behavior). We also investigated SOC strategy use as a moderator in the linkages between IJDs and performance. We sampled three disparate occupational groups (N=4,582). We found that certain dimensions of IJDs showed significant associations with the indicators of job performance but there were also scale-based variations in these linkages, depending on the type of performance and on the sub-scale of IJDs. Specifically, some dimensions of IJDs (e.g., work intensification) related to poorer task performance whereas some other dimensions (e.g., intensified job-related learning demands) related to higher organizational citizenship behaviour. However, SOC strategy use benefitted both types of job performance. Relationships also differed between occupational groups as none of the moderator effects were consistent across the sub-samples.
