INTRODUCTION The Hetero-Anamnestic Personality questionnaire (HAP) is a psychometrically validated instrument for personality assessment by informants (Barendse, Thissen, Rossi, Oei & Van Alphen, 2013). The HAP may generally be completed in ten minutes by an informant such as a child, partner or friend of the patient. The HAP is suitable for assessment of aspects of the personality that are relevant for clinical practice, such as socially avoidant behavior, disorderly behavior and antagonism. The questionnaire can also be used for the screening of personality pathology (Barendse, Rossi & Van Alphen, submitted). The HAP was originally developed in the Netherlands (Barendse & Thissen, 2006) and is now used in a wide range of health institutions for elderly. Clinical practitioners in nursing homes missed tools for personality assessment because self-report of older patients was not possible or not reliable, e.g. because of Alzheimer Disease.  The informant questionnaire is especially developed to address this need. Therefore, it covers the premorbid personality traits. It is of clinical relevance to differentiate between Axis-I disorders, such as dementia, and personality traits, in order to indicate optimal care or clinical services in mental health care. Although not as widespread as in elderly care, the HAP is also used  in the general hospital, rehabilitation center, psychiatric hospital, ambulatory mental health service,  primary care psychology and forensic psychiatry. Separate norms are available for nursing home, geriatric psychiatry and primary care psychology. To respond to the international interest in specific instruments for personality assessment by older adults (Van Alphen, Sadavoy, Derksen, & Rosowsky, 2012)  an English version of the HAP became available. The HAP consists of 62 items with 10 scales and 2 control scales. The ten scales are: Socially avoidant behavior, Uncertain behavior,  Vulnerability in interpersonal relationships, Somatizing behavior, Disorderly behavior, Rigid behavior,  Perfectionist behavior, Antagonistic behavior, Self-satisfied behavior, Unpredictable and impulsive behavior. By using the control scales Positive response tendency and Negative response tendency possible confounding of the results by the response tendencies of the informants can be measured and corrected (Barendse & Thissen, 2006). To stimulate research with the HAP in English-speaking countries the HAP is freely available on request (info@hapsite.nl).
