What type <strong>of</strong> <strong>prevention</strong> did the study investigate (choose only one)? Indicatewhether the study evaluated a primary or secondary <strong>prevention</strong>/intervention. The classicaldefinition <strong>of</strong> primary <strong>prevention</strong> is defined as an intervention aimed at preventing healthypeople from progressing on to symptom or disorder. The classical definition for tertiary<strong>prevention</strong> is defined as intervention aiming to prevent people with clinically recognizeddisorders from further morbidity <strong>and</strong> mortality. Although these definitions are accepted inpublic health literature, to be comparable to other IW&H <strong>review</strong>s, we will use the termsprimary <strong>and</strong> secondary (instead <strong>of</strong> tertiary) for those definitions.To determine what the authors “aimed” to do, <strong>review</strong>ers must only answer based on whatwas reported by the authors. Therefore, any studies where clinical diagnoses or symptoms (aspart <strong>of</strong> a case definition) were used to identify <strong>and</strong> include participants with disorders will beclassified as secondary <strong>prevention</strong>. If a study excluded employees with clinical diagnoses orsymptoms to create a cohort <strong>of</strong> individuals free from symptoms this would be considered aprimary <strong>prevention</strong>. If no such exclusions were made, then the authors will be assumed to76 Institute for Work & Health
