We reviewed construct validity in perception-based methods assessing status and/or trend of forest condition as applied in 19 empirical studies that evaluated the conservation impact of popular participation in forest management. Perception-based methods focus on eliciting peoples&amp;#8217; assessment of the status and/or trend in forest condition or indicators of forest condition through interviews, surveys, or participatory rural appraisal techniques. We found that individual studies generally did not attend to the issue of construct validity in relation to each particular approach to perception-based assessment of status and/or trend in forest condition. Furthermore, the studies provided very little documentation of the construct validity of the...

Qualitative Research: A Grounded Theory Example and Evaluation Criteria
Provedor de dados: 31
Autores: Bitsch,   Vera.
The qualitative research paradigm, although occasionally applied, is not widely discussed in agribusiness and agricultural economics literature. The primary goals of this paper are (a) to present insights into qualitative research approaches and processes by outlining grounded theory as an example of a systematic and rigorous qualitative approach, and (b) to discuss criteria for scientific rigor applicable to qualitative research. In addition, assessing qualitative research is demonstrated by using a published example.

A Comparison of Actual and Hypothetical Willingness to Pay of Parents and Non-Parents for Protecting Infant Health: The Case of Nitrates in Drinking Water
Provedor de dados: 31
Autores: Loomis,   John B.; Bell, Paul; Cooney, Helen; Asmus, Cheryl.
We estimate adults’ willingness to pay (WTP) to reduce health risks to their own or other families’ infants to test for altruism. A conjoint analysis of adults paying for bottled water found marginal WTP for reduction in risk of shock, brain damage, and mortality in the cash treatment of $2, $3.70, and $9.43, respectively. In the hypothetical market these amounts were $14, $26, and $66, indicating substantial hypothetical bias, although not unexpected due to the topic of infant health. Statistical tests confirm a high degree of altruism in our WTP results, and altruism held even when real money was involved.

A Comparison of Actual and Hypothetical Willingness to Pay of Parents and Non-Parents for Protecting Infants' Health: The Case of Nitrates in Drinking Water
Provedor de dados: 31
Autores: Loomis,   John B.; Asmus, Cheryl; Bell, Paul.
The objective of this research was to estimate adults' willingness to pay to reduce health risks to their or other families's infants, the latter to test for altruism. A choice experiment was conducted by having adults pay for bottled water for infants to reduce infants' exposure to nitrates in drinking water. Since nitrates only affect infants' health, we have isolated the adults' willingness to pay just for infants' health by buying bottled water to avoid infants' nitrate intake. Respondents were separated into two treatments, one with hypothetical choices, and the other where respondents were told that one of their four choices would be binding, and they would actually buy bottled water using money given to them at the beginning of the experiment....

Reliability and validity of the interactive observation scale for psychiatric inpatients applied by nursing aides in daily ward practice
Provedor de dados: 56
Autores: Pedrão,L.J.; Hallak,J.E.C.; Bernardo,S.A.; Zuardi,A.W.
The main characteristic of the nursing Interactive Observation Scale for Psychiatric Inpatients (IOSPI) is the necessity of interaction between raters and patients during assessment. The aim of this study was to evaluate the reliability and validity of the scale in the "real" world of daily ward practice and to determine whether the IOSPI can increase the interaction time between raters and patients and influence the raters' opinion about mental illness. All inpatients of a general university hospital psychiatric ward were assessed daily over a period of two months by 9 nursing aides during the morning and afternoon shifts, with 273 pairs of daily observations. Once a week the patients were interviewed by a psychiatrist who filled in the Brief Psychiatric...

Reliability and validity of a Portuguese version of the Young Mania Rating Scale
Provedor de dados: 56
Autores: Vilela,J.A.A.; Crippa,J.A.S.; Del-Ben,C.M.; Loureiro,S.R.
The reliability and validity of a Portuguese version of the Young Mania Rating Scale were evaluated. The original scale was translated into and adapted to Portuguese by the authors. Definitions of clinical manifestations, a semi-structured anchored interview and more explicit rating criteria were added to the scale. Fifty-five adult subjects, aged 18 to 60 years, with a diagnosis of Current Manic Episode according to DSM-III-R criteria were assessed using the Young Mania Rating Scale as well as the Brief Psychiatric Rating Scale in two sessions held at intervals from 7 to 10 days. Good reliability ratings were obtained, with intra-class correlation coefficient of 0.97 for total scores, and levels of agreement above 0.80 (P &lt; 0.001) for all individual...
