Rationale
Precision and Plausability of Hopton and Hunt (1996)
- Reporting bias: Perhaps ít´s difficult to use subjective data due to reporting bias. This is because people may answer in different ways or they don´t answer at all. In addition, people experience household conditions differently.
- Possible confounding variables such as sociodemographic and economic variables, e.g. age and income, were controlled.
- Selection bias: The sample is clearly not representative of the general population and therefore the analysis focuses on differences within the sample. Thus it´s worth considering if the results can be generalized to whole population.
Precision and Plausability of Sidebotham et al. (2002)
- Maltreatment is defined and measured as registration for physical injury, neglect, sexual abuse, emotional abuse. That way all maltreatments, which are not registered are not taken into account.
- The measurement of the social class is not too accurate, because no allowance for nonworking mothers and no parental social class allocated for single mothers can be applied.
- The nature of relationship with child maltreatment is complex (confounder, cultural values, etc). That causes problems in finding an association or causality between an exposure factor and maltreatment. Moreover, maltreatment has different definition in different cultural groups.
- The parental income is not measured directly, but car ownership as a proxy indicator and the receipt of welfare payment are used.
- Controlling for social factors was done.
- Large amount of prospectively data are collected and used in in the study, which is a clear strength.
- The participation is lower among the maltreated group, which might influence the outcome of the statistical analysis or bias the results of the study.
- The risk of social bias and no way of measuring the effect of such bias. A social bias can be defined as a prejudgement of a specific social group. In this case, it might be that those, who collected the data might have expectations, that parents which lower or higher social background are more prone to maltreat their child and let this expectation influence their interpretation of the results. This is not very likely here, though, because all parameters which were used for the analysis can me measured and there is not much freedome for interpretation.
Precision and Plausability of Packer et al. (1994)
- health problems: possibility of headache, mental problems, emotional reactions, social isolation and pain.
- social factors: unemployment, single parent, lone adult and unemployment with sickness or disability
- lifestyle: consumption of alcohol and smoking
----#: . It might be helpful for the reader if you would use full sentences in order to explain how the above issues affect the precision and plausibility of ERF. --Marjo 15:28, 4 February 2013 (EET) (type: truth; paradigms: science: comment)
- it is still difficult to understand the housing condition because none of the studies are complete and detailed so that direct comparison with the questions cannot be made and measurements of parameters, potential confounding factors as well as clear dose-response relationship should be adjusted for example physical effect of damp is responsible for muscle tension, backache and headache but on the other hand the study poins out that there is a strong relationship between damp housing and adverse health impact. ----#: . I see that the two last points are in concordance with each other. --Marjo 15:28, 4 February 2013 (EET) (type: truth; paradigms: science: comment)
Precision and Plausability of Blackman et al. (2001)
- Bias in respondents answers to realistically evaluate their and family members health.←--#: . Good. --Marjo 16:25, 7 February 2013 (EET) (type: truth; paradigms: science: defence)
- Some housings that where targets on first survey were demolished during second survey.
- No data from comparison neighbourhood without renewal to back up observed health changes after renewal program. ←--#: . Good point. --Marjo 16:25, 7 February 2013 (EET) (type: truth; paradigms: science: defence)
- Relationship between dampness, draughts and mental health is uncertain, because the mechanism is unknown.←--#: . Again good, although you could specify this. Is it so that associations have been found but the mechanisms are unclear? --Marjo 16:25, 7 February 2013 (EET) (type: truth; paradigms: science: defence)
- Multivariate analysis using regression model was used to control variables, such as economic, housing, respiratory and mental health related to increase plausability----#: . So in contrast to the previous points, this increases the plausibility of ERF, is this what you mean? --Marjo 16:25, 7 February 2013 (EET) (type: truth; paradigms: science: comment)
----#: . Precisions and plausabilities updated --Jukka Hirvonen 09:30, 11 February 2013 (EET) (type: truth; paradigms: science: comment)
Precision and Plausability of D. Fanning (1967)
- The study is so old that the exposures and responses are real but the accuracy is quite poor. The basics are almost same as today but measurement techniques are so old that the results are not comparable to modern results. ⇤--#: . Which specific measurement techniques do you mean? For example, they have measured first attendances by general practitioners, and I don´t think the accuracy of counting has changed significantly. --Marjo 18:08, 8 February 2013 (EET) (type: truth; paradigms: science: attack)←--#: . However, I agree with you that the oldness of study is a bit striking. Probably today many other parameters in addition to those used in the article would be measured when conducting this kind of study. --Marjo 18:08, 8 February 2013 (EET) (type: truth; paradigms: science: defence)
- The study has considered the difference between children and adults.←--#: . Good point. --Marjo 18:08, 8 February 2013 (EET) (type: truth; paradigms: science: defence)
- The study has not considered the differences between different flats and houses. They have only categories for houses and flats but the differences between houses are not considered. This causes bias to the study.----#: . Well, it is possible. However, it is always a question of e.g. resources how specific and detailed a study can be. Maybe they could more apparently mention whether there were any significant dissimilarities between houses. --Marjo 18:08, 8 February 2013 (EET) (type: truth; paradigms: science: comment)
Precision and Plausability of Petticrew et al. (2009)
- Data collection at the three occassions in the intervention group before moving, one year after moving and 2 years after moving to the social housing gives strenght to the study in analysing changes in the housing circumstances and in neighbourhood.
- Recruitment into the study was discussed by the landlord to the tenant once they have accepted the housing offer which dosn't gives the RSL direct contact with the participant though this serves as a way of good recruitments but it dose not guarantee the authenticity of the data collected. e.g RSL couldn't supply the number of people who refuse to participate in the study to the SHARP research team.
- Broad range of adult household categories in the intervention group which was used as a base for recruiting the comparism group stenghthen the study. (family households, with children under age of sixteen years, older households where the respondents and adult members of the households were of pensionable age, and adult households with a combination of relationships, including parents with children atleast 16 years of age, people unrelated to one and another and couples )
- Qualitative and quantitative findings were only presented for 1 year(wave 2) in the study which dose not proof if the effects are sustained and probabely if differences in health outcomes occur at two years in the intervention and comparism groups.
- recollection bias may occur during interview if participant in the groups if they can not recall adequately past occurences relating to health, housing and neighbourhood questions after one year and two years of movement to the new house.
- Bias in subsequent analysis can also occur if there is any significant changes in the groups associated with self reported health.
←--#: . Good points and thorough work! By checking the spelling you could increase the elegancy of your work. --Marjo 17:46, 11 February 2013 (EET) (type: truth; paradigms: science: defence)----#: . updated --Matthew 12:43, 13 February 2013 (EET) (type: truth; paradigms: science: comment)
Precision and Plausibility of Pollack et al. (2004)
Since the study controls which can potentially bias the result,like socioeconomic factors,relation to the neighbors,pollution in the local environment,I can say the result is is ok.Besides multiple questioners were performed to assess the home and neighborhood environment again to reduce bias.But I have comments which can potentially affect the result,and which is not discussed in detail or not mentioned at all in the article
-If the participants work, of-course, they have to work to survive ,how about the condition of task place they work,does it have a potential to influence in their health? since the average time per day a person spent in a task is about 8hr,which is about one third of the day, so it supposed to be considered in detail. That is my argument
-How about life style,diet,smoking,alcohol,may be they included it in socioeconomic factor,in this case we have to get the detail information and parameters about the topics in socioeconomic factors.
In summary they put huge effort to come up to the result but further clarity required,and I can say it is OK regardless of plausibility and precision. ←--#: . Good considerations. Correcting the language would increase the elegancy of your work. --Marjo 16:35, 14 February 2013 (EET) (type: truth; paradigms: science: defence)
