Suicidal intent, hopelessness and depression in a parasuicide population: the influence of social desirability and elapsed time.

This paper reports the first British study to assess the construct validity of Beck's Hopelessness Scale (HS) and the Beck Depression Inventory (BDI). On the basis of interviews with 50 economically active parasuicide patients, it was confirmed that hopelessness accounts for the relationship between depression and suicidal intent. Moreover, it was shown that social desirability neither confounds the relationship between hopelessness and suicidal intent, nor has any predictive power in explaining variation in suicidal intent. On the other hand, the interval ('elapsed time') between the commencement of the parasuicidal act and of the research interview was significantly and positively correlated with suicidal intent, and elapsed time was a significant predictor of the total score on Beck's Suicidal Intent Scale. Two explanations for this finding are proposed: the first is based on the possibility that elapsed time is an indirect or proxy measure of medical seriousness; the second derives from the likely impact of prolonged hospital stay on the patient's interpretation or understanding of his/her behaviour. Researchers are advised to take into account the moderating effect of elapsed time when designing studies which examine psychological processes in parasuicide.

Rhetorical intentionality attribution: its ontogenesis in ordinary conversation.

This paper addresses the assumption that the epistemological dichotomy between reality and its construction is an everyday rhetorical tool children and adults use in their explanations and arguments. Within a discursive psychology perspective, the phenomenon of attribution of rhetorical intentionality (AIR) is theoretically defined developing the notion of prepackaged interest attribution technique (Edwards & Potter, 1992). AIR consists in an explanation of others' discursive moves in terms of a rhetorical-argumentative activity; that is, in terms of a deliberate attempt aimed at construing and presenting reality as a function of the speaker's point of view, perspective and interests, in order to affect the listeners mental state (belief, knowledge, intention) or action. Theoretical links are made to the theory of mind paradigm in the study of intentionality attribution, particularly to the form of life approach which defines intentionality attribution in terms of language games. On this basis, the present study examines the structures and functions of AIR used by children and their parents in everyday conversation. Qualitative discourse analysis of transcripts of 22 dinner conversations from eight Italian families shows explicit and implicit AIR in children from three and a half to seven years of age. Moreover, parents attribute rhetorical intentionality to their children, contributing to their social construction as rhetorical speakers. AIR is used as a rhetorical strategy within disputes and argumentative contexts, often achieving topic closure. Results are discussed with reference to the ontological status of intentionalist talk.

Efficient on-line setup correction strategies using plan-intent functions.

With the introduction of image-guided radiation therapy (IGRT) delivery systems on-line set-up correction strategies have gained in popularity. Usually, the correction workload of these strategies is high compared to off-line strategies as daily setup corrections have to be performed based on a predefined action level. In this work, it is proposed that on-line strategies must not only be judged in terms of workload but also in terms of efficacy. While workload can be easily predicted for such strategies, the efficacy must ultimately reflect the efficiency with which the original treatment plan intent is met. The purpose of this work is to investigate the tradeoff between workload and efficacy of three different on-line set-up correction strategies: The common fixed action level strategy and two novel on-line setup correction strategies, i.e., a dose-volume histogram (DVH) constraint and an equivalent uniform dose (EUD) score strategy that aim directly for better compliance with original treatment plan intent. All strategies were reformulated in terms of a score function that reflected treatment plan intent. A retrospective study was conducted on 5 prostate patients (7-field conformal, 79.8 Gy, 42 fractions). PTV margins were 10 mm except in the posterior direction (7 mm). The original treatment plan intent for these patients was defined using a set of DVH constraints. The results show that the on-line setup correction strategy based on a fixed action level of 3 mm resulted in a considerable correction workload. For larger action levels, a dose benefit (in terms of EUD) in the rectum and bladder was observed for all patients which is clinically "fortuitous" but difficult to take advantage of. In contrast, the application of the two novel strategies generally resulted in a controlled decrease of the dose to the rectum and the bladder with a smaller workload. It is concluded that using information about target anatomy and the planned dose distribution allows the design of specific correction strategies that are better tailored to the individual patient and that comply effectively with initial treatment plan intent.

Medical malpractice: the effect of doctor-patient relations on medical patient perceptions and malpractice intentions.

OBJECTIVE: To examine the causal effects of doctor-patient relations and the severity of a medical outcome on medical patient perceptions and malpractice intentions in the event of an adverse medical outcome. DESIGN: Randomized between-subjects experimental design. Patients were given scenarios depicting interactions between an obstetric patient and her physician throughout the patient's pregnancy, labor, and delivery. PARTICIPANTS: One hundred twenty-eight postpartum obstetric patients were approached for participation, of whom 104 completed the study. Main outcome measures Patients' perceptions of physician competence and intentions to file a malpractice claim. RESULTS: Positive physician communication behaviors increased patients' perceptions of physician competence and decreased malpractice claim intentions toward both the physician and the hospital. A more severe outcome increased only patients' intentions to sue the hospital. CONCLUSION: These results provide empiric evidence for a direct, causal effect of the doctor-patient relationship on medical patients' treatment perceptions and malpractice claim intentions in the event of an adverse medical outcome.

Racial segregation and county level intentional injury in Pennsylvania: analysis of hospital discharge data for 1997-1999.

STUDY OBJECTIVE: This study examined whether high levels of racial segregation are associated with high county level intentional injury rates. DESIGN: Multiple linear regression was used to assess the association between county racial segregation (measured by the Gini coefficient) and intentional injury rates. Multicollinearity was assessed with Eigenvalues and condition indices. SETTING: State of Pennsylvania. PATIENTS: County level intentional injury rates for 1995 to 1997 were calculated from hospital discharge data. MAIN RESULTS: After controlling for other known county level risk factors, higher levels of racial segregation in a county were significantly related to higher intentional injury rates. Multicollinearity was not a problem. Population size and density, family stability and median income, together with the percentage male, unemployed, in poverty, divorced men, and high school graduates of the county were controlled. CONCLUSIONS: Racial segregation is an important factor in the rate of intentional injury in a community. These results may be important for municipal and state agencies when developing public policies to prevent violence and promote racial integration.

Associations of SF-36 mental health functioning and work and family related factors with intentions to retire early among employees.

OBJECTIVE: To examine the associations of mental health functioning (SF-36) and work and family related psychosocial factors with intentions to retire early. METHODS: Cross sectional survey data (n = 5037) from the Helsinki Health Study occupational cohort in 2001 and 2002 were used. Intentions to retire early were inquired with a question: "Have you considered retiring before normal retirement age?" Mental health functioning was measured by the Short Form 36 (SF-36) mental component summary (MCS). Work and family related psychosocial factors included job demands and job control, procedural and relational justice, conflicts between work and family, and social network size. Multinomial regression models were used to analyse the data. RESULTS: Poor mental health functioning, unfavourable psychosocial working conditions, and conflicts between work and family were individually related to intentions to retire early. After adjustments for all work and family related factors the odds ratio for low mental health functioning was halved (from OR = 6.05 to 3.67), but nevertheless the association between poor mental health functioning and strong intentions to retire early remained strong. CONCLUSIONS: These findings highlight not only the importance of low mental health and unfavourable working conditions but also the simultaneous impact of conflicts between work and family to employees' intentions to retire early.

Predictors of intentions to stop smoking early in prenatal care.

OBJECTIVE: To determine baseline variables associated with low intentions of stopping smoking early in pregnancy. DESIGN: Cross sectional survey. PARTICIPANTS: Pregnant smokers pooled across seven Smoke-Free Families trials (n = 1314). RESULTS: 36% of pregnant smokers had low intentions of stopping smoking within the next 30 days. In contrast to pregnant smokers with higher intentions of quitting, pregnant smokers with low intentions were less confident in their ability to quit, less likely to have private health insurance, and less likely to agree that smoking harms the unborn child. They were more likely to smoke heavily, more likely to have fewer years of education, and more likely to have friends and family members who smoke. CONCLUSIONS: Three options to smoking cessation assistance are proposed for pregnant smokers with low intentions of quitting: targeting, triage, and tailoring. Further research is needed to determine which approach is most appropriate.

Colorectal cancer screening with faecal occult blood testing: community intention, knowledge, beliefs and behaviour.

The objective of this study was to examine the current community intention, knowledge, beliefs and behaviour regarding colorectal cancer (CRC) screening with faecal occult blood testing (FOBT). A cross sectional telephone survey of the general population was conducted in Queensland, Australia. A random sample of 1,136 residents aged 40-80 years were invited to participate in the survey with a response rate of 77.8%. 77.5% (95% confidence interval [95% CI]: 74.0 to 80.7%) of respondents reported that they would participate in CRC screening by FOBT if recommended to do so by doctors or health authorities. Screening intention was significantly associated with interest in further information concerning CRC or CRC screening (odds ratio: 6.7; 95% CI: 3.4 - 13.1), belief that CRC screening is necessary for persons without symptoms (5.0; 95% CI: 1.5 -17.1), and belief that treating bowel cancer in the early stages increases a person's chance of survival (5.1; 95% CI: 2.6 - 9.9). Knowledge of seeking medical advice (2.8; 95% CI: 0.9 - 8.7) and diarrhoea/constipation as a symptom of CRC (1.7; 95% CI: 0.9 - 3.2), self-initiated screening behaviour (1.5; 95% CI: 0.8 -2.9), and medical check a couple of times a year or more (2.4; 95% CI: 0.9 - 6.5) were also marginally significantly associated with screening intention. Community intention to screen for CRC with FOBT may have increased over recent years. Screening intention is associated with community knowledge, attitudes/beliefs and behaviour.

Predicting breast-feeding intention among low-income pregnant women: a comparison of two theoretical models.

This study examined the applicability of the transtheoretical model and a model derived from the theory of reasoned action for predicting breast-feeding intention among low-income pregnant women. Participants completed a 70-item self-report questionnaire assessing their breast-feeding attitudes, intentions, and support. A positive correlation existed between Stages of Change for breast-feeding and the number of Processes of Change used by respondents. A negative correlation existed between Stages of Change for breast-feeding and the number of negative breast-feeding beliefs held by respondents. Furthermore, women's normative beliefs and outcome beliefs were significantly correlated with breast-feeding intention in manners consistent with the model developed from the theory of reasoned action. After accounting for significant sociodemographic and lifestyle factors, the Processes of Change and outcome beliefs remained independently correlated with breast-feeding intention. These models are capable of predicting the intention to breast-feed and might offer an innovative approach for further breast-feeding research and intervention development.

Modelling the cost implications of using carboxymethylcellulose dressing compared with gauze in the management of surgical wounds healing by secondary intention in the US and UK.

OBJECTIVE: To estimate the costs of using carboxymethyl cellulose dressing (CMCD; Aquacel* Hydrofiber) compared to gauze in managing surgical wounds healing by secondary intention in the US and UK. STUDY DESIGN: This was a modelling study performed from the perspective of payers (i.e. the hospital and community sector in the US and the National Health Service (NHS) in the UK). METHODS: Clinical outcomes attributable to managing surgical wounds healing by secondary intention with gauze were obtained from the published literature in the English language. There were no published studies on wounds healing by secondary intention with CMCD. Hence, the analysis conservatively assumed that wound healing rates associated with gauze would be the same for CMCD. These data were combined with resource utilisation estimates derived from a panel of clinicians enabling us to perform decision modelling. The models were used to determine the expected direct healthcare costs eight weeks after the surgical wounds were dressed by CMCD or gauze and left to heal by secondary intention in the US and UK. RESULTS: All wounds are expected to heal within eight weeks, irrespective of dressing. Managing abscesses and other surgical wounds with CMCD instead of gauze in the US is expected to reduce costs by 4% in both wound types (i.e. $247 and $507 respectively) per patient over eight weeks. In the UK, managing abscesses and other surgical wounds with CMCD instead of gauze is expected to reduce costs by 30% (574 pounds) and 12% (581 pounds) respectively per patient over eight weeks. The lower cost of managing CMCD-treated patients is due to decreased nursing costs associated with a lower frequency of CMCD changes compared to gauze dressing changes. CONCLUSION: Dressing surgical wounds healing by secondary intention with CMCD instead of gauze is expected to lead to a reduction in healthcare costs in both the US and UK. Hence, the purchase price of a dressing is not indicative of the cost effectiveness of a given method of surgical wound care.

Intention tremor during manual aiming: a study of eye and hand movements.

Accurate goal-directed movements toward a visual target require a precise coordination of both the oculomotor and limb motor systems. Intention tremor and eye movement deficits are frequently observed in multiple sclerosis (MS). The goal of this study was to examine the characteristics of intention tremor and simultaneously produced eye movements during rapid goal-directed movements. Eye and hand movements were synchronously measured in 16 MS patients with intention tremor and 16 control subjects. Manual performances of the patient group were characterized by a delayed onset, slower execution and aiming inaccuracies. In line with the clinically defined picture of intention tremor differences between patients and control subjects were most pronounced toward the end of the movement. Dependent variables were obviously greater in MS patients compared with control subjects, and correlated well with clinical outcome measures. The application of an inertial load to the limb did not show any effect on intention tremor. In addition to impaired limb coordination, evidence has been found that eye movements, too, were abnormal in patients compared with control subjects. Moreover, eye and hand movement deficits seemed to be closely related, suggesting a common underlying command structure. Inaccurate eye movements were likely to hamper an accurate motor performance of the hand.

Hopelessness, depression and suicidal intent in parasuicide.

Previous work on the inter-relationships among depression, hopelessness and suicidal intent in parasuicide is reviewed. Our own study of 120 hospital-referred parasuicides confirms previous findings that, while both depression and hopelessness correlate with the degree of suicidal intent as measured on a Suicide Intent Scale, the relationship between depression and suicidal intent is dependent on that between hopelessness and suicidal intent. Some practical and theoretical implications are discussed.

Life stress, medical lethality, and suicidal intent.

Eighty parasuicide patients were studied. The importance of life stress, age, and General Health Questionnaire score as predictors of the suicidal intent and medical lethality which they exhibited was examined. Medical lethality and suicidal intent were closely related: those whose parasuicide resulted in high lethality differed from those showing low lethality in their degree of suicidal intent, but did not differ in life stress, age, or GHQ score. Although both life stress and GHQ score were significantly correlated with suicidal intent, the GHQ score accounted for a greater proportion of the variance. These results suggest a more complex relationship between life stress, GHQ score, and suicidal intent than is often assumed.

Intention of residents in internal medicine to care for patients infected with HIV at a university hospital in Taiwan.

The purpose of this study was to investigate internal medicine residents' HIV-related knowledge and their attitudes towards caring for HIV-infected patients, and determine the extent to which these variables influence their care-providing intention. A cross-sectional survey was conducted in 56 internal medicine residents at a university hospital in Taiwan. Results showed residents' lack of sufficient knowledge was reflected by their inaccurate assessment of HIV-associated risk and their tendency to overuse protective gear in unnecessary situations. In general, residents expressed slightly positive attitudes with a neutral intention to care for HIV-infected patients. Knowledge and attitudes were significantly correlated with intention. The use of stepwise regression analysis revealed attitudes accounted for 59% of the variance in intention. Future efforts should focus on designing, implementing, and evaluating educational programmes that address residents' needs to ensure a solid HIV-related knowledge base, support their positive attitudes, address their ambivalent feelings toward providing HIV care, and enhance their intention to care for HIV-infected patients.

Correlates of negative intent to receive an AIDS vaccine: an exploratory study.

Our objective was to investigate demographic, behavioural, and psychosocial correlates of negative intent to receive a hypothetical AIDS vaccine. A cross-sectional survey was conducted of 278 adults from three populations: gay men, African-American women, and persons who used illicit drugs (including injectable drugs). Twenty percent of the sample expressed negative intent. In controlled analyses, negative intent was significantly more likely among people reporting they had not had sex (past year) (P = 0.01), people who reported they worried about 'problems' that could be caused by an AIDS vaccine (P = 0.006), and those never diagnosed with a sexually transmitted disease (P = 0.04). Finally, although significance was marginal, persons reporting they had not had a flu vaccination in the past five years were about 1.9 times more likely to have negative intent (P = 0.055). Among this demographically diverse sample, behavioural and psychosocial (rather than demographic measures) were associated with negative intent to receive an AIDS vaccine.

Salient beliefs and intentions to prescribe antibiotics for patients with a sore throat.

OBJECTIVES: General practitioners (GPs) in the UK continue to prescribe antibiotics for patients with sore throats despite evidence that they are ineffective and can contribute to the growth of antibiotic resistance in the population. This study uses the theory of planned behaviour (TPB) to investigate the strength of intention to prescribe antibiotics, and to identify the salient beliefs associated with this intention. DESIGN: Cross-sectional study testing hypotheses derived from the TPB. METHOD: A 66-item postal questionnaire was distributed to a random sample of GPs in one NHS region (N = 185). The questionnaire included measures of intention to prescribe antibiotics, attitude, behavioural beliefs and evaluations, normative beliefs and evaluations, perceived behavioural control, control beliefs, and past prescribing. RESULTS: Two-thirds of the GPs returned complete questionnaires (N = 126, 68%). The majority intended to prescribe antibiotics for less than half of their patients with sore throats (N = 69, 55%). The variables specified in TPB predicted 48% of the variance in intention, with past behaviour adding a further 15%. Seven salient beliefs distinguished between doctors who intend to prescribe antibiotics and those who do not. CONCLUSIONS: Attitudes towards antibiotics and control beliefs are important predictors of intention to prescribe, as predicted by TPB. Interventions could target salient beliefs associated with motivation to prescribe.

Beliefs and attitudes associated with the intention to not accept the diagnosis of depression among young adults.

PURPOSE: Negative attitudes and beliefs about depression treatment may prevent many young adults from accepting a diagnosis and treatment for depression. We undertook a study to determine the association between depressive symptom severity, beliefs about and attitudes toward treatment, subjective social norms, and past behavior on the intent not to accept a physician's diagnosis of depression. METHODS: We conducted a cross-sectional study of 10,962 persons aged 16 to 29 years who participated and had positive screening results on the Center for Epidemiologic Studies Depression (CES-D) score in an Internet-based public health depression screening program. Participants reported whether they would accept their physician's diagnosis of depression. Based on the theory of reasoned action, we developed a multivariate model of the factors that predict intent not to accept a diagnosis of depression. RESULTS: Twenty-six percent of the participants stated their intent not to accept their physician's diagnosis of depression. Disagreeing that medications are effective in treating depression (strongly disagree, odds ratio ( OR ) = 6.5, 95% confidence interval (CI), 4.6-9.3), that there is a biological cause for depression (strongly disagree, OR = 1.9, 95% CI, 1.3-2.7), and agreeing that you would be embarrassed if your friends knew you had depression were associated with the intent not to accept a diagnosis of depression (strongly agree, OR = 2.3, 95% CI, 1.8-2.9). Beliefs and attitudes, subjective social norms, and past behavior explained most of the variance in this model (84%). CONCLUSIONS: Negative beliefs and attitudes, subjective social norms, and lack of past helpful treatment experiences are associated with the intent to not accept the diagnosis of depression and may contribute to low rates of treatment among young adults.

Follow-up and surveillance of the lung cancer patient following curative-intent therapy.

The following two distinctly different issues should be taken into account when planning patient care following curative-intent therapy for lung cancer: adequate follow-up to manage complications related to the curative-intent therapy; and surveillance to detect recurrences of the primary lung cancer and/or development of a new primary lung cancer early enough to allow potentially curative retreatment. Follow-up for complications should be performed by the specialist responsible for the curative-intent therapy and should last 3 to 6 months. Recurrences of the original lung cancer will be more likely during the first 2 years after curative-intent therapy, but there will be an increased lifelong risk of approximately 1 to 2% per year of developing a metachronous, or new primary, lung cancer. A standard surveillance program for these patients is recommended based on periodic visits, with chest-imaging studies and counseling patients on symptom recognition. Whether subgroups of patients with a higher risk of developing a metachronous lung cancer (eg, those patients whose primary lung cancer was radiographically occult or central and those patients surviving for > 2 years after treatment for small cell lung cancer) should have a more intensive surveillance program is presently unclear. The surveillance program should be coordinated by a multidisciplinary tumor board and overseen by the physician who diagnosed and initiated therapy for the original lung cancer. Smoking cessation is recommended for all patients following curative-intent therapy for lung cancer.
