Disease is a phenomenon that becomes part of family life producing structural, procedural and emotional changes that affect family health; this is understood as the family\'s ability to function and adapt to stressful life events, which include the illness or disability of any of its members ([@bib0095], [@bib0125]). Different authors have tried to explain the psychological phases that families go through when a member is diagnosed with a condition. In these situations families usually have a period of crisis that is followed by a period of post-crisis, which are influenced by different modulate variables, such as illness characteristics, family background, perception of situation, family burden, resources, and other capabilities including resilence, hardiness, coping, and other family characteristics such as cohesion, flexibility, communication, organization or mutually supportive relationships ([@bib0095], [@bib0115], [@bib0120], [@bib0190]). The families tend to adapt to illness by way of normalization strategies to integrate this situation into daily family life. In this sense, both mastery and routinization of the treatment are important aspects of family\'s response to illness ([@bib0125]).

The family disease management could be defined as daily behavior that families perform to manage and adapt when a member is diagnosed with a condition ([@bib0120]) and aims at generating a positive family environment, with emotional stability and ways of coping appropriately that allow the patient and all family members to adapt to the crisis and obtain the services and resources needed. So that, families must initiate strategies aimed at coping with the impact of the illness or disability on the patient by offering support and assistance, at obtaining the necessary normalization to continue functioning and to minimize its consequences for other family members, and also must actively participate in the health care provided to the sick member ([@bib0085], [@bib0140]).

Conceptual definition of the construct under assessment {#sec0005}
=======================================================

Nursing outcomes classification (NOC) for family health domain, was used as a reference, from which family support during treatment, family normalization and family participation in professional care outcomes were selected ([@bib0135]). NOC is a standardized classification of health outcomes, which has previously been used in designing clinometric instruments ([@bib0185]). We considered that family disease management should be oriented to achieve the named outcomes given that they refer to key elements related to disease management, i.e., sick person, his/her family, and family participation in professional care.

Family support is related to the functions of support and care, providing for the patient\'s well-being and independence, and assisting in disease surveillance, decision-making and implementation of appropriate actions. The family should maintain good communication and empathy, provide information, material and emotional assistance, thus meeting the patient\'s basic needs. Previous studies have shown that the people with higher levels of family support have better adherence to the regime, better management of disease and lower hospitalization rates ([@bib0230]).

Family normalization starts acknowledging the new condition of the sick or disabled member and the potential changes needed to manage this situation ([@bib0125]). It is related to changes in family functioning and organization, in which family has to be flexible in the performance of family roles, in modifying the family routine and housing conditions if necessary, and adjust their resources and apply for help for the extended family as well as the existing community social services ([@bib0020]). Previous research showed the importance of including the care of the sick or disabled member in daily family life, especially for sick children and chronic disease ([@bib0075]).

Family participation in the care process is particularly necessary in the case of children, disabilities or mental illness, terminally ill patients, etc., where the family should be involved in taking decisions about who to consult, when or where to go for treatment. The family is responsible for managing the sick person\'s day to day life, accompanying them regularly to the care professional or during hospitalization, providing key support to the professional in the communication with the patient, and identifying the factors that affect attendance and the attitudes and behaviors that are most effective for coping with the problem ([@bib0210], [@bib0250]); and the participation of the family in the care plan is also a positive motivator in achieving results ([@bib0040], [@bib0195]).

Different instruments were designed to measure different aspects relating to family health, focused mainly on family functioning, stressing life events or strategies for coping with these situations ([Table 1](#tbl0010){ref-type="table"}). We could point the Family APGAR ([@bib0065]), the Family Cohesion and Adaptability Evaluation Scale ([@bib0190]), the Social Climate Scale ([@bib0175]), or the Family Management Measure for Families of Children with Chronic Conditions ([@bib0120]).Table 1Scales for assess family needs: Literature review.Reference*Instrument, dimensions, population, psychometric proprieties assessment*[@bib0015]Family Functioning, Health and Social Support 62 items;

We are unaware of the existence of a general instrument aimed at assessing family disease management where there is a sick or disabled member; and previous authors have stated the value of designing and validating new instruments where there are no others that assess the construct that it is really sought to measure ([@bib0055]). This instrument could be useful for having a better understanding of the common challenges experienced by families in these situations, making it easier to compare family management across different conditions rather than a specific one ([@bib0120]).

Construction and qualitative assessment {#sec0010}
=======================================

We performed an exhaustive literature review of family health and family management (Psycinfo, Pubmed, Scopus, and Web of Science) to clarify and develop the main concepts. The originally Family Disease Management scale was designed, consisting on 36 items and three dimensions of family support, family normalization and family participation with twelve each in dimension. A content validation by a quali-quantitative study was performed using an on-line Delphi panel as a consensus technique with eighteen experts on the study topic, including doctors, nurses and psychologists. The degree of adequacy of each item was established, according to five-points Likert-scale; the opportunity to suggest new items or propose amendments was also offered. The items were assessed according to the following criteria: Validated: mean ≥ 3.5 and median ≥ 3 and high ratings (4-5) ≥ 80% and/or standard deviation ≤ 0.90. Eliminated: mean \<3.5 and median \<3. Finally, it took a total of two rounds to reach the necessary level of consensus and to refine a 30-items scale ([@bib0135]).

The aim of the present work was to study the factor structure (Confirmatory Factor Analysis \[CFA\]) and the internal consistence of the Family Disease Management Scale. Taking into account the theoretical and empirical issues previously discussed we hypothesize a one-dimensional construct (Family Disease Management) with three sub-dimensions, family support, family normalization, and family participation in the care process ([Figure 1](#fig0005){ref-type="fig"}).Figure 1Family Disease Management (construct under assessment).

Method {#sec0015}
======

Participants {#sec0020}
------------

The sample size was arrived following the recommendations of over 200 individuals to perform the confirmatory factor analysis ([@bib0180]). Finally, an intentional sample of 392 households of two or more members with sick or disabled members was interviewed. The interviewee was a caregiver, adult (more than 18 years of age). Those that showed cognitive decline were excluded. The households had an average size of 4.4 members. Most of them were nuclear (50%) or extended families (24%). Regarding the stage of family life cycle, 25.5% were middle age parents and 25% had adolescent children. Rest of descriptions is shown in [Table 2](#tbl0015){ref-type="table"}.Table 2Descriptive for the sample.*n (%)Interviewee gender* Male151 (38.55) Female241 (61.45)  *Family relationship* Spouse106 (27.04) Father/mother181 (46.17) Son/daughter95 (24.23) Son/daughter in-law8 (2.04) Sibling1 (0.26) Grandson/granddaughter1 (0.26)  *Type of family* Nuclear196 (50) Extended94 (24) Extended nuclear43 (11) Single-parent51 (13) Binuclear/reconstructed8 (2)  *Family Life Cycle Stage* Married couple (no children)4 (1.02) Preschool children2 (0.51) School children25 (6.36) Teenagers96 (24.49) Young adults living at home80 (20.41) Middle-age parents100 (25.51) Ageing family members85 (21.67) Stage transition66 (16.84)  *Interviewee age* Mean (SD)58.18 (15.99)  *Number of members* Mean (SD)4.40 (1.66)

Instrument {#sec0025}
----------

In order to characterize the sample we asked questions about composition, typology, and the Family Life Cycle Stage. The 30-item Family Disease Management scale was used for testing its psychometric properties ([Appendix 1](#sec0060){ref-type="sec"}).

Data collection and procedure {#sec0030}
-----------------------------

It took place between October 2012 and November 2013. A self-administered format was used by interviewers previously trained at health centers belonging to the Andalusian Health Service or family homes. Anonymity, confidentiality and data protection were guaranteed, by using informed consent. The study was approved by the ethics committee of the University of Seville.

Statistical analysis {#sec0035}
--------------------

We performed a CFA with AMOS 22.0. This provides an appropriate statistical framework to evaluate psychometric properties where there is a clear idea of the scale dimensionality and specific hypotheses that relate indicators and latent dimensions ([@bib0030]). In fact, there are precedents for using this technique in both validating new scales ([@bib0050]) and transcultural adaption of scales ([@bib0145]). Different factor solutions were tested, a first formula with 30 items characterized by a one-dimensional construct (family disease management), a second formula with 30 items characterized by three first-order factors (support, normalization, and participation) and one second-order factor (family disease management), and a third formula with 29 items characterized by three first-order factors (support, normalization, and participation) and one second-order factor (family disease management). In this last formula, empirical modifications to the reference models were introduced taking into account changes in modification indices, goodness of fit indices and factorial charges, and regarding the results this showed a better fit. The Kaiser-Meyer-Olkin index (KMO) and Bartlett\'s test of sphericity were examined, whose results greater than .80 and levels of significance lower than .001 respectively indicated the appropriateness of conducting CFA. In addition, we used Mardia\'s coefficient ([@bib0045]), considering multivariate normal distribution if this coefficient is lower than p (p + 2) where p is a number of observed variables (30 observed variables).

Goodness of fit indices. We examined the magnitude *χ*^2^ to chose the model in which this is smaller; the discrepancy divided by its degrees of freedom (CMIN/DF \[should be lower than 3\]); Root Mean Square Error of Approximation (RMSEA\<.08); Incremental fit index (IFI); Normed fit index (NFI); Comparative Fit Index (CFI); Tucker-Lewis Index (TLI); Parsimony ratio (PRATIO). The values of these indices should be close to .90 to be considered a good fit. Information Criterion (AIC) and Expected Cross-Validation Index (ECVI) were calculated, indicating the lower the values, the better the fit ([@bib0005], [@bib0105], [@bib0225], [@bib0240]). Regarding internal consistence, we tested whether the Cronbach\'s alpha coefficient became greater if an item was deleted, and we considered that reliability indices located around .80 are adequate. We analyzed the discrimination index of corrected item-total correlations that should be higher than 1/√k (k = number of items) ([@bib0180]). We tried to confirm internal consistency and each item\'s contribution to the respective examination\'s total score of three different models. Analysis was carried out with SPSS 22.0.

Results {#sec0040}

Factor structure {#sec0045}
----------------

The KMO was .92 and Bartlett\'s test showed non-significant values (*p* = .000). In the first model, family disease management was considered as a one-dimensional construct determined by 30 observed variables (items) \[[Figure 2](#fig0010){ref-type="fig"}\]. Factor loadings ranged between .23 (item 11) and .76 (item 5) whereas measurement errors ranged between .05 (item 11) and .58 (item 5). Only PRATIO = .93 indicates a possible fit ([Table 3](#tbl0020){ref-type="table"}).Figure 2Model 1.

We then tested a second model, more potentially plausible, determining three first-order factors (support, normalization and participation), each one measured by ten items, with these first-order factors all loading onto one higher-order factor (family disease management) \[[Figure 3](#fig0015){ref-type="fig"}\]. Factor loadings ranged between .24 (item 11) and .81 (item 5) whereas measurement errors ranged between .06 (item 11) and .65 (item 5). The amount of variance explained by the latent traits ranged between .91 and .96. This model showed a better fit, close to being acceptable.Figure 3Model 2. Hierarchical model with three first-order factors onto one higher-order factor.

Finally, we introduced several sequential empirical modifications, by re-examining the results, and we tested a third model consisted of factor solutions with three first-order factors that involved 29 items (support with ten items, normalization with eleven items and participation with eight) loading onto one higher-order factor (family disease management). Modification indices suggested the liberalization of the covariance between seven par error measures, those corresponding to par e1\*e2 (*r* = .25, *p*\<.001), par e5\*e6 (*r* = .56, *p*\<.001), par e12\*e13 and par e13\*e14 (*r* = .24, *p*\<.001), par e16\*e17 (*r* = .39, *p*\<.001), par e19\*e20 (*r* = .47, *p*\<.001), and par e27\*e28 (*r* = .35, *p*\<.001) \[[Figure 4](#fig0020){ref-type="fig"}\]. The factor loadings ranged between .27 (item 22) and 0.78 (item 5) whereas measurement errors ranged between .07 (item 22) and .61 (item 5). The amount of variance explained by the latent traits ranged between .87 and .95. This model showed the best goodness of fit indices as can be seen in [Table 3](#tbl0020){ref-type="table"}.Figure 4Model 3. Hierarchical model with three first-order factors onto one higher-order factor.

Internal consistency reliability {#sec0050}
--------------------------------

In the three models tested Cronbach\'s Alpha was higher than .70 for the whole scale and subscales. It was stable or decreased if an item was deleted, except for item 22 in the participation subscale (in both model 2 and 3). Moreover, corrected item-total correlation coefficients were higher than 1/√k, except in item-11 (model 1 and model 2) and item 22 in the three tested models. For the rest of the items, coefficients were higher than .40 ([Table 4](#tbl0025){ref-type="table"}, [Table 5](#tbl0030){ref-type="table"}).Table 4Descriptive and internal consistency reliability of Models 1 and 2.*DescriptiveModel 1Model 2MeanStandard*\

Discussion {#sec0055}
==========

A scale designed to measure family disease management in families with sick or disabled members was assessed. The psychometric properties were tested in a large sample of families of different composition, type, and stages of the family life cycle; this sample was consistent with the indications from previous which gives more power and strength to the validation process. On the other hand, the analysis of internal consistency values have been appropriated according to the recommendations, as reliability indices located around around α = .80 are adequate for diagnosis or classification ([@bib0180]).

Regarding the factor structure the suitability of three models was tested; and the third hierarchical model showed the best goodness of fit indices. This involved 29 items with three first-order factors that represent the constructs, family support, family normalization and family participation, where these three factors deposit all the load onto another higher order called family disease management. In this model, items 1 to 10 assess family support; items 12 to 20, 25 and 26 assess family normalization; and items 21 to 29 family participation. The factor loads of all items were above .40, with significant values, except item 22 but it was maintained to improve its goodness of fit.

The family support subscale assesses basic help functions and the necessary demands for obtaining good family support, being related to adherence to therapeutic regime, control and management of the disease ([@bib0115], [@bib0230]). The family normalization subscale assesses the way the family adapts to meet the daily needs of the patient and the rest of its members, which contribute to improved normal functioning, satisfaction and family caregivers' health, and strengthen families by allowing them to take the necessary measures to meet emerging needs, reducing their levels of family concern ([@bib0020], [@bib0085], [@bib0125]). Finally, the family participation subscale assesses how the family is involved in the care process, either participating in or accompanying and maintaining the system support to the sick relative, significantly contributing to professional practice ([@bib0040], [@bib0195]).

Limitations. First, although previous authors state the goodness of CFA for testing psychometric properties ([@bib0030]), it might be appropriate to carry out previously other techniques regarding classical test theory, including exploratory factorial analysis. Second, although we accepted the third model as more adequate regarding goodness of fit indices proposed, other authors proposed stricter cut-off points such as RMSEA\<.05 whereas TLI and CFI greater than .95 ([@bib0010]), and in our study these indices have reached .066, .870 and .882 respectively. Third, the external validity of the instrument, including cross-validation techniques, is not shown and should be carried out in future research. Fourth, we did not ask about the kind and grade or the number of years of disease/disability of the sick family member and it could be interesting for comparing family disease management regarding these factors.

In spite of limitations, this study provides evidence of factor structure and internal consistence of a scale and subscales designed to evaluate family disease management. The instrument provides specific indicators to measure family support to a sick or disabled family member, family normalization and family participation in the care process. This scale could be useful for clinical practice, since the family is the main provider of care; and for epidemiological studies and other types of research in the field of management, planning and assistance.
