THE THEORY OF WORK ADJUSTMENT (TWA), WHICH PROVIDES A CONCEPTUAL FRAMEWORK FOR RESEARCH IN WORK ADJUSTMENT, HAS BEEN TESTED, CRITICIZED, AND RECENTLY RESTATED. TWA ASSUMES THAT EACH INDIVIDUAL SEEKS TO ACHIEVE AND MAINTAIN CORRESPONDENCE WITH HIS ENVIRONMENT. CORRESPONDENCE IS DEFINED AS A HARMONIOUS RELATIONSHIP AND MUTUAL SUITABILITY BETWEEN THE INDIVIDUAL AND HIS ENVIRONMENT. IN THE CASE OF WORK, CORRESPONDENCE IS DESCRIBED IN TERMS OF THE INDIVIDUAL FULFILLING THE REQUIREMENTS OF THE WORK ENVIRONMENT, AND THE WORK ENVIRONMENT FULFILLING THE REQUIREMENTS OF THE INDIVIDUAL. THE STABILITY OF THIS CORRESPONDENCE IS MANIFESTED AS JOB TENURE. THE LEVELS OF SATISFACTORINESS AND SATISFACTION (SS), FOR INDIVIDUALS WITH SUBSTANTIAL TENURE IN A SPECIFIC WORK ENVIRONMENT, ESTABLISHES THE LIMITS OF SS FROM WHICH TENURE CAN BE PREDICTED FOR OTHER INDIVIDUALS ONCE THEIR NECESSARILY STABLE WORK PERSONALITIES HAVE BEEN ASSESSED. INSTRUMENTS WERE DEVELOPED TO MEASURE--(1) WORK RELEVANT NEEDS OF INDIVIDUALS, (2) OCCUPATIONAL REINFORCER SYSTEMS OF JOBS, (3) INTERMEDIATE WORK ADJUSTMENT SHORT OF TENURE, AND (4) SATISFACTORINESS SCALES. THE VOCATIONAL COUNSELOR CAN NOW MORE PRECISELY DETERMINE WHAT JOBS ARE MOST LIKELY TO FACILITATE CLIENT SS. A LIST OF THE FORMAL PROPOSITIONS OF TWA ARE INCLUDED. THIS PAPER WAS PRESENTED AT THE AMERICAN PSYCHOLOGICAL ASSOCIATION CONVENTION, WASHINGTON, D.C., SEPTEMBER 5, 1967. (PR)
