          Abstract

          Summary Objective: In order to introduce an instrument within our midst that allows a comprehensive clinical evaluation of pain-induced depression in the elderly, we proposed the translation, cross-cultural adaptation into Brazilian Portuguese, and study of the psychometric properties of the “Geriatric Psychosocial Assessment of Pain-induced Depression” (GEAP) scale. This instrument was especially developed for the screening of depression associated with chronic pain in the elderly. Method: We performed translation and cross-cultural adaptation of the GEAP scale, whose psychometric properties were analyzed in a sample of 48 elderly individuals. Sociodemographic data and information related to chronic pain were ascertained, as well as those related to depression. The GEAP-b scale was applied at three different times on the same day by two different interviewers (I1 and I2), and after 15 days by one of those interviewers (I3). Results: The GEAP-b proved to be an easy-to-apply instrument with a high internal consistency value, according to the Cronbach’s alpha coefficient (0.835). The reproducibility of the instrument was optimal, achieving intraclass correlations of 98.5 and 92% for interobserver and intraobserver, respectively. There was “considerable” agreement (between 0.419 and 1.0) for each GEAP-b item, except for item 19, according to the kappa statistic. As for the validity of the GEAP-b criterion, positive and statistically significant correlations were obtained for pain, according to GPM-p (r=49.5%, p<0.001), and depression, according to GDS (r=59%, p<0.001), both values being considered regular (between 40-60%). Conclusion: The GEAP-b scale has proven to be reliable and valid in the screening of pain-related depression in the elderly.

          Resumo Objetivo: A fim de se introduzir no nosso meio um instrumento que permitisse uma avaliação clínica abrangente da depressão dor-induzida em idosos, propôs-se a tradução, adaptação transcultural para o Brasil e estudo das propriedades psicométricas do “Geriatric Psychosocial Assessment of Pain-induced Depression” (GEAP). Esse instrumento foi desenvolvido especialmente para rastreio da depressão associada à dor em idosos. Método: Foram realizadas tradução e adaptação transcultural do GEAP, cujas propriedades psicométricas foram analisadas em uma amostra de 48 idosos. Foram apurados dados sociodemográficos e relacionados a dor crônica, além de depressão. O GEAP-b foi aplicado em três momentos distintos, em um mesmo dia por dois entrevistadores diferentes (E1 e E2), e após 15 dias por um daqueles entrevistadores (E3). Resultados: O instrumento GEAP-b mostrou-se ser de fácil aplicação e alto valor de consistência interna, de acordo com o coeficiente alfa de Cronbach (0,835). Teve reprodutibilidade ótima, segundo as correlações intraclasses: valores de 98,5 e 92%, interobservador e intraobservador, respectivamente. As concordâncias para cada item do GEAP-b foram “consideráveis“ (entre 0,419 e 1,0), excetuando-se a concordância para o item 19, segundo a estatística kappa. Para a validade de critério do GEAP-b, correlações positivas e estatisticamente significativas foram obtidas para a dor, segundo o GPM-p (r=49,5%; p<0,001), e para a depressão, segundo o GDS (r=59%; p<0,001), com ambos os valores considerados regulares (entre 40 e 60%). Conclusão: O GEAP-b demonstrou ser confiável e válido no rastreio da depressão associada à dor em idosos.

          The measurement of postoperative pain: a comparison of intensity scales in younger and older surgical patients.

          The psychometric properties of pain intensity scales for the assessment of postoperative pain across the adult lifespan have not been reported. The objective of this study was to compare the feasibility and validity of the Numeric Rating Scale (NRS), Verbal Descriptor Scale (VDS), and Visual Analog Scale (horizontal (VAS-H) and vertical (VAS-V) line orientation) for the assessment of pain intensity in younger and older surgical patients. At 24h following surgery, 504 patients, who were receiving i.v. morphine via patient-controlled analgesia, completed the pain intensity measures and the McGill Pain Questionnaire (MPQ) in a randomized order. They were asked which scale was easiest to complete, the most accurate measure, and which they would most prefer to complete in the future, as an index of face validity. The amount of opioid self-administered was recorded. Age differences in postoperative pain intensity were not found. However, elderly patients obtained lower MPQ scores and self-administered less morphine than younger people. Psychometric analyses suggested that the NRS was the preferred pain intensity scale. It had low error rates, and higher face, convergent, divergent and criterion validity than the other scales. Most importantly, its properties were not age-related. The VDS also had a favourable profile with low error rates and good face, convergent and criterion validity. Finally, difficulties with VAS use among the elderly were identified, including high rates of unscorable data and low face validity. Its use with elderly postoperative patients should be discouraged.

            An epidemiologic comparison of pain complaints.

            A survey concerning common pain conditions and psychological distress was carried out among a probability sample of the adult enrollees of a large health maintenance organization in Seattle. The prevalence of pain in the prior six months was 41% for back pain; 26% for headache; 17% for abdominal pain; 12% for chest pain; and 12% for facial pain. Headache, abdominal and facial pain were less prevalent among older persons and more prevalent among females. We examined the temporal dimensions of these pain conditions, as well as intensity, treatment seeking, and activity limitation. The pain conditions were typically long standing, recurrent, of mild to moderate intensity, and usually did not limit activities. However, depending on the pain condition, 9-40% reported one or more days in the prior six months when they were unable to carry out their usual activities due to the pain problem. On average, persons with a pain condition had higher levels of anxiety, depression, and non-pain somatic symptoms as measured by the scales of the Symptom Checklist (SCL); poorer self-rating of health status; and more family stress compared to persons without a pain condition. Of these alternative measures of distress, the SCL somatization scale had the strongest independent association with pain. The increments in measures of anxiety, depression, and family stress with the presence of pain were greatest among persons with higher levels of non-pain somatic symptoms.

              Factors that modify the association between knee pain and mobility limitation in older women: the Women's Health and Aging Study.

              To investigate the influence of pain severity, knee extensor muscle weakness, obesity, depression, and activity on the association between recent knee pain and limitation of usual and fast paced walking, and ability to rise from a chair. A cross sectional analysis of 769 older women (mean age 77.8, range 65-101) with physical disability, but no severe cognitive impairment. Severity of knee pain in the past month was classified as none, moderate, or severe. Mobility was measured using timed performance tests. The prevalence of recent knee pain was 53% (408/769). One third of the women with pain reported it to be severe. In general, knee pain was only significantly associated with limited mobility if severe. Obesity, activity and, to a lesser extent, depression intensified the effects of pain. Knee extensor weakness did not. Obesity was a distinctive risk factor in that it substantially increased the risk of mobility limitation, but only in women with pain. In women who had severe pain, activity (walking more than three city blocks in the past week) increased the risk of walking disability more than inactivity. Depression had a minor, but statistically significant effect on walking ability, but not the ability to rise from a chair. In older women with recent knee pain, a high pain severity score, obesity, and activity are important factors that increase the risk of mobility limitation.
