This paper outlines a methodological approach to examining individual wellbeing within married couples that incorporates each partner’s allocation of time. Drawing on data from the Sample Survey of Daily Time Use by the Population (orig. Выборочное наблюдение использования суточного фонда времени населением 2024), we construct multiple‑indicator, multiple‑cause (MIMIC) models using ALR‑transformed time‑use regressors to identify the association between wellbeing and the relative redistribution of time. Wellbeing, treated as a latent construct, is operationalised through indicators of human capital (health status and educational attainment) and material resources (income). The results demonstrate a robust and statistically significant relationship between wellbeing and the time‑allocation decisions made by individuals and their partners. The analysis also reveals gendered patterns in this relationship, alongside differences between weekends and working days. The proposed integrated approach enables the estimation of partners’ wellbeing – despite its inherently non-observable nature – while explicitly accounting for each partner’s time allocation.
time allocation, wellbeing, time budgets, married couples, gendered division of labour
In contemporary research on the wellbeing and quality of life of married couples, comparatively little attention has been paid to the allocation of spouses’ time budgets. Yet partners’ decisions about how to distribute time between paid work, housework, childcare, leisure, and other activities reflect not only individual preferences and priorities, but also social norms, structural constraints, and gendered expectations. Analysing how spouses allocate their time therefore provides important insights into how the organisation of daily life is associated with wellbeing. However, the nature of the relationship between the structure of a family’s time budget and the wellbeing of its members remains insufficiently understood.
A number of studies have demonstrated links between one partner’s time allocation and various aspects of the other’s wellbeing. For example, family functioning and wellbeing are closely associated with work schedules (
Employment status also plays a significant role: unemployed individuals report lower levels of life satisfaction than those in work (
Among dual‑earner couples, higher levels of marital satisfaction and a more equitable division of domestic responsibilities are more commonly observed (
Gender inequality in the distribution of time and men’s participation in domestic tasks is also highly relevant to wellbeing. Men’s involvement in housework and childcare has been shown to enhance their wives’ wellbeing (
Beyond the structure of time allocation itself, researchers also examine how time is spent – whether jointly or separately. Time spent together is particularly important for happiness and overall life satisfaction (
Taken together, existing research demonstrates that an individual’s wellbeing is shaped not only by their own lifestyle, as reflected in their time allocation, but also by their partner’s. Differences in the time spouses devote to work, housework and other activities constitute important determinants of individual wellbeing. In this context, examining the temporal determinants of wellbeing using Russian data is particularly timely.
In this study, we test – using Russian data for the first time – the hypothesis that an individual’s wellbeing is associated with both their own time allocation and that of their spouse.
To test the hypothesis that time allocation within couples is associated with individual wellbeing, we draw on data from the Sample Survey on the Use of Daily Time by the Population, conducted by Rosstat in 2024. The analysis includes observations for individuals aged 20 and over who reported the distribution of their daily time across seven broad activity categories, with a minimum total of 720 minutes (12 hours) per day. Observations in which reported time spent on sleep and paid employment exceeded 1.000 minutes (approximately 16 hours) per day were treated as outliers and excluded from the analysis.
From the full dataset, we selected individuals in registered marriages for whom information on their spouse was available. The household types included in the sample were restricted to ‘married couple’ and ‘married couple with children under 18’. This restriction reflects the aim of the study, which is to identify the association between wellbeing and time allocation among married couples. After applying the selection criteria, the final sample comprised 14.682 couples on weekdays and 14.812 couples at weekends.
The variables used in the analysis are presented in Table
| Variable | Description |
| income | Average monthly monetary income per household member, in roubles |
| health | Self-assessment of health status, where 1 = very poor, 5 = very good |
| education | Educational attainment level, where 1 = no basic general education, 8 = highest qualification (postgraduate studies, doctoral studies) |
| age | Respondent’s age |
| territory | Respondent’s place of residence, where 1 = city, 0 = village |
| family | Household composition, number of people |
| have_ch | Identifier for individuals with children aged 0–14, where 0 = no children of that age, 1 = children of that age are present |

In this study, wellbeing is treated as a characteristic that cannot be observed directly but is inferred from a limited, yet theoretically grounded, set of observable indicators. Following the author’s previous work, health status, educational attainment, and income are used as indicators of wellbeing (
In the literature, each of these measures is traditionally regarded as a core dimension of wellbeing (Stiglitz et al. 2009; OECD 2013; World Bank, 1980). Income shapes access to material resources (
Although these indicators do not capture the full breadth of wellbeing, they represent fundamental and widely applicable dimensions that reflect its multidimensional nature. Accordingly, the following variables are used as indicators of the latent wellbeing variable:
Average income per household member is used as the indicator of material wellbeing due to data availability. Expressing this variable in units of the cost of a region-specific fixed basket of goods and services (2024) ensures comparability across the constituent entities of the Russian Federation.
A distinctive feature of time‑use data is their compositional nature: the sum of all time‑use components is constrained by the 24‑hour day (1.440 minutes). An increase in time devoted to one activity necessarily reduces the time available for others, which rules out the independence of potential regressors (
This study examines seven broad activity categories:
A detailed description of the specific activities included in each category is provided in Table
Time spent on travel, educational activities and other forms of employment not included in these categories is excluded from the analysis. The standard deviation of total reported time was 72 minutes for women and 77 minutes for men on working days, and 87 and 94 minutes respectively on days off. In this dataset, the sum of the selected activity categories does not equal 24 hours, meaning that the data constitute a ‘partial composition’ (
To interpret the results in terms of the redistribution of time across activities, we apply the additive log‑ratio (ALR) transformation. This transformation enables the analysis of the relative structure of time allocation by comparing each component (activity category) with a chosen baseline (
Following the transformation, each component is expressed as the logarithm of its ratio to the baseline component:
,
where xi is the time (in hours) spent on the i-th activity, and xD is the time (in hours) spent sleeping (the baseline activity).
The use of these transformed time‑use variables enables the findings to be interpreted in terms of the redistribution of time across different activities.
When applying this approach, particular attention must be paid to the presence of zeros in the data, as these make the transformation impossible (ln0 is undefined) (
Variables with more than 80 per cent zero values were excluded from the composition and entered into the model as separate regressors in their original units (hours). For example, for men on both working days and days off, the childcare variable was excluded; for both men and women on days off, the paid‑employment variable was excluded. To assess the robustness of the results, additional specifications using a lower threshold of 60 per cent zero values were estimated.

To examine the nature of the association between unobserved wellbeing and time allocation, we estimate multiple‑indicator, multiple‑cause (MIMIC) models (
The choice of this modelling strategy rests on the assumption that wellbeing is multidimensional. Unlike alternative approaches, the MIMIC framework does not require selecting a single measure of wellbeing or constructing a composite index in advance. Instead, the latent variable is estimated on the basis that each indicator represents an incomplete manifestation of the underlying construct. A key advantage of the model is the simultaneous estimation of parameters for both the measurement and structural components within a single framework, while accounting for measurement error. In sequential analytical approaches, measurement error is typically ignored at the regression stage.
Formally, the measurement component can be expressed as follows:
y = Λ wellbeing + ε,
where y is the vector of indicators of the unobserved wellbeing variable, Λ is the vector of factor loadings, wellbeing is the unobserved (latent) wellbeing variable, and ε is the vector of measurement errors.
.
To ensure comparability of scales, all indicators were first standardised using the scale function in R. For model identification, the unstandardised factor loading of the first indicator (income) was set at 1. Standardised factor loadings are used in the interpretation of the results, as they indicate the extent to which each indicator reflects variation in the latent wellbeing construct.
The structural component of the model includes the following causes:
The structural part of the model is specified as follows:
wellbeing = ΓTX + ζ,
where Γ is the vector of coefficients for the observed factors, Х is the vector of observed factors, and ζ is the error term of the structural part.
.
The variables containing alr_w represent the transformed time‑use regressors for women, while those with alr_h denote the corresponding regressors for men. The variable h_child captures the time men spend on childcare in its original units (hours). It should be noted that the components of vector X may vary depending on the day of the week.
In general form, the multiple‑indicator, multiple‑cause model can be represented as the following system:
.
The model was estimated using maximum likelihood, implemented via the R lavaan package (
It should be emphasised that, within this methodological framework, the results are interpreted solely in terms of association (presence and direction) whilst causal effects are not specified, owing to potential endogeneity.

All estimated models exhibit relatively high values of the root mean square error of approximation (RMSEA), exceeding the commonly recommended threshold of 0.08. However, high Comparative Fit Index (CFI) and Tucker–Lewis Index (TLI) values, together with low Standardised Root Mean Square Residual (SRMR) values, indicate that the models fit the data well overall.
Because the time‑use variables were transformed using the ALR method, the interpretation of the coefficients for these regressors is as follows: a positive coefficient indicates that an increase in the ratio of time spent on the activity in question to time spent sleeping is associated with a higher level of latent wellbeing; a negative coefficient indicates an association with lower wellbeing.
For women on working days, an increase in the ratio of time spent in paid employment relative to sleep is associated with higher wellbeing, whereas increases in the ratios for housework and activities for own final use are associated with lower wellbeing. Viewed in this light, the ‘double burden’ borne by women may have a negative impact on their wellbeing.
A husband’s redistribution of time towards paid employment is positively associated with his wife’s wellbeing on working days, while a redistribution towards activities for his own final use is negatively associated with it.
On days off, a shift in time allocation towards any form of activity – whether paid work or housework – is associated with lower wellbeing for women. A positive association is observed only for ‘personal hygiene and self‑care,’ which includes activities related to restoring energy and health. A husband’s engagement in activities on his day off (whether paid or unpaid for his own final use) is likewise negatively associated with his wife’s wellbeing.
For men, the pattern of associations differs markedly. Time allocated to paid employment on working days is positively associated with the latent wellbeing variable, which may reflect aspirations for professional fulfilment and the material wellbeing of the household. A positive association – albeit weaker than paid employment – is also observed for activities such as housework and work for own final use. This may be interpreted as a beneficial effect of participating in the shared management of household affairs.
Conversely, a greater time burden on wives is negatively associated with men’s wellbeing: the more time a wife allocates to paid work and domestic duties (relative to sleep), the lower, on average, her husband’s wellbeing. In other words, a wife’s overwork – both in the labour market and within the household – is associated with reduced wellbeing for her spouse. By contrast, a relative increase in the time a wife devotes to self‑care is positively associated with her husband’s wellbeing.
On days off, the time men spend in paid employment becomes less salient, while their involvement in household chores and activities for their own personal use is positively associated with wellbeing. An increase in the time wives spend on paid work and housework on days off continues to be associated, on average, with lower wellbeing among husbands.
Taken together, across all four specifications, the results indicate that on working days a wife’s wellbeing is associated with both her own labour‑market participation and her husband’s employment. At the same time, a husband’s wellbeing is, on average, lower when his wife carries a heavy workload – whether in paid employment or in housework. At weekends, any redistribution of women’s time towards labour activities (relative to sleep) is negatively associated with both their own wellbeing and that of their husbands. By contrast, women’s engagement in self‑care activities is positively associated with the wellbeing of both partners.
Regarding basic sociodemographic characteristics, household size is not significant for latent wellbeing in most specifications. Living in an urban area is positively associated with the latent variable, which may reflect the benefits of better developed infrastructure. The presence of children aged 0–14 is not significant in any of the estimated models.
This study applied a methodological framework to estimate the association between latent wellbeing and time allocation within married couples. Drawing on ALR‑transformed time‑use data from the 2024 Sample Survey of Daily Time Use by the Population enabled assessing how the relative allocation of spouses’ time is associated with individual wellbeing.
The MIMIC models revealed consistent associations between the composite wellbeing measure and spouses’ time‑allocation decisions, with particular attention to gender differences in how time devoted to specific activities relates to wellbeing.
For women, wellbeing on working days is positively associated with a relative increase in time spent in paid employment, suggesting the importance of self‑fulfilment through work. Greater involvement in housework and activities for own final use, however, is associated with lower wellbeing, indicating that the ‘double burden’ may have a detrimental effect. On weekends, higher wellbeing among women is associated with refraining from both paid and unpaid work in favour of self‑care and recuperation.
For men, wellbeing on working days is more strongly associated with paid employment, consistent with the traditional breadwinner role. However, a wife’s heavy workload – both in the labour market and in the household, relative to her recovery time – is negatively associated with her husband’s wellbeing. Notably, on days off, men’s participation in household duties is positively associated with his individual wellbeing, whereas high levels of wives’ involvement are negatively associated with it. Overall, women’s wellbeing appears to depend on achieving a balance between work and recovery, while men’s wellbeing is linked to the extent of their wives’ workload.
The proposed conceptualisation of latent wellbeing brings together fundamental, widely applicable and accessible indicators, avoiding the reduction of wellbeing to a single measure. Nonetheless, it does not capture the full diversity of wellbeing outcomes, such as subjective happiness, life satisfaction, or satisfaction with specific life domains.
Although the use of transformed time variables addressed the compositional nature of the data, further comparison with models based on original (absolute) indicators, as well as analyses of associations between wellbeing and participation in specific activities, would be valuable for testing the robustness of the findings. Future research should also examine more closely the role of children in the household. In this study, the presence of children was not significant in any specification, which may reflect variation in associations depending on the child’s age. In the original dataset, more than 80 per cent of men reported zero time spent on childcare. Identifying subgroups of families with non‑zero childcare time would allow for a more nuanced interpretation.
At this stage, the results suggest that the balance of time allocation is an important factor in the wellbeing of each spouse. The proposed approach offers a basis for further investigation of the multidimensional construct of wellbeing, taking into account patterns of time allocation across different household types.
