" (Ibid) Stated is that improvements in model fit "were indicated by a decreasing BIC with each successive model as classes were added and completion of the model estimation was at the point the BIC showed a rise. A descriptive analysis was conducted as well which states that "overall there was a trend toward poorer levels of SRH with each successive data collection wave." (Ibid) Stated is that the unbalanced data was handled by Latent GOLD which estimated models through use of information that was available for "each of the response patterns." Stated is that each "case with complete baseline data contributed to the model solution. (Vermunt & Magidson, 2003) The final model selected was on the bases of theory as well as interpretation statically. It is stated that the classes within the 'three-class' model "would reflect distinct, but overlapping profiles of SRH, which could be labeled as positive health (PH) average health (AH) and negative health (NH). The PH profile...
Reports from the AH profile were rated very good, good and fair, all middle range reports.
XIV. STRENGTHS/LIMITATIONS
Strengths in this study are that use of existing data saves time, costs and resources and the ability to "study larger, more representative samples and include more variables; and opportunities to examine data from a different theoretical perspective" as well as making provisions of support for primary studies in the future. (Moriarity, et al. 1999 as cited by Finnegan, Marion & Cox, 2004) Limitations of the study are stated to be are the measurement error and endogeneity. There was limited scope in measuring some of the variables of the study due to the "availability of appropriate indicators" (Ibid) Furthermore endogeneity is stated confound relationships between the time-varying predictor variables…

Nursing: Review of Quantitative Research
Nurse led clinical research: neonatal nurses' perceptions and experiences The aims of the study are to understand the experiences of clinical nurses in conducting and utilizing clinical research within their neonatal setting. This is a qualitative study of five neonatal nurses who were interviewed using semi-structured, face-to-face interviews to obtain the study data. This was a phenomenology-based study, which means it was meant to study the overall structure of the nurses experiences
Quantitative Research Critique Part I Introduction It is important to note, from the onset, that the health and wellbeing of women is often impacted upon negatively by intimate partner violence (IPV). In the past, various research studies have attempted to not only assess the impact of IPV on the health and wellbeing of women, but also the strategies that ought to be implemented in seeking to care for victims of IPV. In
Validity, in essence, has got to do with the extent to which a given research study measures the accuracy of a specific concept – effectively meaning that a study can be said to have passed the validity test if it accurately mirrors that which the researchers set about to investigate. In quantitative research, as Polit and Beck (2012) point out, “researchers strive to design studies that are strong with respect
nursing research: Discussion questions Quantitative research includes descriptive, correlative, quasi-experimentational, and experimentational research (Burns 2010: 21). Descriptive research describes a phenomenon, purely and simply. Correlative research attempts to determine if there is a correlation between two types of phenomenon (such as a correlation between participation in athletic sports and overweight adolescents' decrease in BMI). Quasi-experimental research may have a 'control group' in the real world (such as overweight adolescents who
Assessing the quality of quantitative research Question 1: Study purpose/question (a) Did the study have a clearly stated purpose/research question? Yes (b) Explain your response below: The study was designed to evaluate the feasibility of the mobile service so as to determine the most suitable sample size and to refine
(1) 7 Identification and Control of Extraneous Variables What are the extraneous variables in this study? (1) In what way(s) were appropriate measures used to control for the influence of the extraneous variables? (1) 2 Study Instruments/Tools Identify the type of each measurement strategy (i.e. Likert scale, visual analog scale, physiological Measure, questionnaire, observation, or interview). (1) Identify the level of measurement (nominal, ordinal, interval/ratio) achieved by each measurement strategy. (1) Discuss how the instrument was developed or
